match-data aborts on mac os x

match-data aborts on mac os x

[bryan o'connor]

[current cvs emacs built for mac os x --with-carbon]

my emacs process dies with a call to abort().  while it has happened
in different situations, i can faithfully recreate it using SLIME and
slime-edit-definition (M-.) three times in a row.

i think i've isolated the problem to the changes made to match-data in
v1.181 (6/23/2004) of src/search.c.  i have no problems running from
sources dated 6/22.

i will continue to look into it, but i'm hoping that the author of
the change might have some suggestions.

thanks,

		...bryan

There have been more changes at 06/29 and 06/30.  Your search.c is
newer than that?

If it is, could you run Emacs under gdb and give a backtrace when it
bugs out?

i just tested a cvs version dated 6/28 and it did abort().  the 
backtrace
is attached below.

my keystrokes were:
	M-x slime [return]
	M-. prin1 [return]
	M-. prin1 [return]
	M-. prin1 [return]

I have repeatedly stated that I had no clue what I was doing there, as
I have no idea how Lisp data structures are implemented in C.  I have
begged in desperation that someone take a look at the patch before I
check it in.

No reaction.  So that's where we are now.

Does the following patch (where I, on a hunch, try using XSETBUFFER
whenever assigning a buffer, without a clue about whether this has any
relevance or not) change anything?

unfortunately no difference.  the backtrace looks similar.

Actually, reconsidering that mad patch, I'd expect Emacs to more or
less dump core continuously with that.

What about "your search.c is newer than that?" did you not understand?
I just went on bug search for hours and now on rereading all posts for
further hints I finally notice that you did not even bother to get the
version I explicitly told you had relevant fixes in it.

i thought my first post was clear, my initial bug report was based on
a fresh cvs version from today.

i explicitly tested 6/28 to show that the 6/29 and 6/30 changes did
not introduce the bug.

Then that was a misunderstanding.  Those changes _fixed_ a similar
bug, I was not expecting them to be the cause of it.  You are
positive that you have not accidentally missed out on a recompilation
or whatever else when reporting the problem with the current CVS?

Anyway, I don't have slime here.  It would appear that the data
structure it passes to set-match-data is rejected.  Can you verify in
the source whether all calls to set-match-data operate with
unmodified data from a call of match-data?

Undo the patch.  Does the following patch help in any manner?

that fixed it.  i just did a fresh checkout + your patch + bootstrap

If anybody on this list had bothered commenting on my "in particular,
I have no clue what would be needed for the garbage collector" plea,
it would have saved me quite a bit of time.

I am checking this in now.

Compile with -DUSE_LISP_UNION_TYPE -DENABLE_CHECKING so you'll get
compile-time and runtime checking.  Once the compilation goes through you
can drop the -DUSE_LISP_UNION_TYPE (it costs run-time performance with no
additional run-time checking).
