With current trunk bootstrapped an hour ago

GNU Emacs 24.0.50.1 (i386-mingw-nt5.1.2600)
  of 2011-09-05 on NESTOR

I get the backtraces below.

It might be related to a change I introduced back in June: I now (#8)
run_window_configuration_change_hook when doing x_set_tool_bar_lines
something we didn't do earlier.  Personally, I don't care whether we run
it but since adding/removing the toolbar changes the sizes of window(s)
it should be run, in principle.  But maybe something hasn't been set up
yet correctly so the abort triggers ...

I don't think so.  It's something more weird, see below.

> #1  0x011e5ef1 in bidi_initialize () at bidi.c:762

This crashes here:

  bidi_mirror_table = uniprop_table (intern ("mirroring"));
  if (NILP (bidi_mirror_table))
    abort ();    <<<<<<<<<<<<<<<<<<<<<<<

It should never happen that uniprop_table returns nil.  Something is
badly broken in the build.

Was this during startup, when Emacs was creating its first frame?
Because otherwise, I don't understand how come it called
bidi_initialize at this time: it should be called whenever the first
redisplay cycle, ever, is entered, which happens during startup.

If I can reproduce this, I will take a look.

Nope, cannot reproduce this.  Emacs starts OK for me, and displays
both the initial frame and HELLO correctly.  If I set a breakpoint in
bidi_initialize, I see a non-nil value being returned by
uniprop_table.

Do you have a good uni-mirrored.el file in lisp/international?  What
is its size?  Could it be that bootstrapping somehow messed up that
file?

It comes up normally here too and I can view HELLO.  But it aborts when
run under the debugger.

No idea.  It has 9342 bytes.

Under the debugger, does it abort before completely displaying the
initial frame?  Or is that frame already displayed when it aborts?

Also, what version of the debugger do you have?

And how did you configure Emacs? what options to configure.bat did you
use?

That's the size I have here.

Recreate it?

I'm bootstrapping a clean tree and will see if I can find out
something that way.

No cigar, a fresh bootstrapped build works both with and without the
debugger.

What unusual things did you have there?  Is that "emacs -Q", or is
some customizations involved?

No initial frame shown.

GNU gdb 6.8.

I get the same behavior with a build from about two weeks ago and a
correspondingly different file.

OK, at least this is as expected.

Perhaps upgrade to a later version (7.3 is already available from
MinGW site).

Again, only under GDB?

Does it help to load uni-mirrored.el explicitly, as in "run -l
../lisp/international/uni-mirrored.el" from GDB prompt to run Emacs
(assuming you run GDB from the src directory)?

Anyway, it looks like Emacs is unable to load uni-mirrored.el, I get
the same crash if I rename the file.  So perhaps put a breakpoint in
Fload and see what's going on there when it tries to load
uni-mirrored.el.

Yes.  I get a crash with a certain scenario and in order to investigate
that crash I want to run emacs under the debugger.  Unfortunately, I do
not get very far there.

gdb --args c:/emacs/quickfixes/bin/emacs.exe -l c:/emacs/quickfixes/lisp/international/uni-mirrored.el

or

gdb --args c:/emacs/quickfixes/bin/emacs.exe -l ../lisp/international/uni-mirrored.el

give the same backtrace.

How?  I don't know when it tries to load uni-mirrored.el.

Like this:

 (gdb) break bidi_iniialize
 (gdb) r -Q

When this breakpoint breaks, step through bidi_iniialize until you get
to the 2nd uniprop_table call.  Then type at GDB prompt:

 (gdb) break Fload
 (gdb) continue

The next break in Fload should show that Emacs is loading
uni-mirrored.el.  You can verify that once Fload breaks like this:

 (gdb) pp file

Then step through Fload and see which line fails there.

Note that in order for "pp" to work, you will need to start GDB in the
src directory.  But you probably already know that.

What is the value of Vload_source_file_function?  If it's
load-with-code-conversion (as I think it should be), then either add
(message foo) printouts in load-with-code-conversion and see what
happens there, or put a breakpoint in Finsert_file_contents, which
load-with-code-conversion eventually calls, and see why that fails.

If this is after you invoked Emacs from GDB (as opposed to attaching
to a running program), then I guess it's a bug in that old port of GDB
you are using.  It works for me in v7.2.

Anyway, you can use this less convenient method instead:

 (gdb) p file
 (gdb) xstring

(This assumes that `file' is a Lisp string.  There's `xtype' to show
the type.)

Fine.  I now know what happens but don't understand why.  I'm running
the debugger from an older emacs and `insert-file-contents' loads
uni-mirrored.el from the directory of _that_ emacs.  This also explains
why I see the abort only when running under gdb.  If I run gdb from the
new emacs, the debugged emacs starts as expected.

Thanks for helping so far, but I suppose something must be fixed here.

... unless the bug is in my gdb, obviously.  In that case we probably
should strongly warn people to use such a version.

This is a feature ;-)  You will see in w32.c that Emacs sets
EMACSLOADPATH in the environment to the path it creates from known
directories, in order to set load-path correctly.  And GDB probably
inherits that exports it to the Emacs being debugged...

We define EMACSLOADPATH in the environment because the Windows build
doesn't want to depend on PATH_LOADSEARCH macro being set at build
time (in epaths.h), since the compiled binary needs to be able to run
on a different machine.  See init_lread.

Perhaps we should remove EMACSLOADPATH from process-environment when
we run inferior subprocesses?

It's obvious to me now but it was absolutely confusing initially.

Some help for cross-debugging would be needed.  A minute ago my
debugging emacs crashed on an already crashed debugged emacs.

Does it help to say "unset environment EMACSLOADPATH" at the GDB
prompt, before starting Emacs under the debugger?

What does "show environment" print after the unset command?
