random crashing with bootstrap emacs (cvs) under solaris (SunOS 5.8)

random crashing with bootstrap emacs (cvs) under solaris (SunOS 5.8)

[Mark Aufflick]

Hi,



I have been trying for some time to get emacs cvs compiled on Solaris.



When I get to the stage of make bootstrap where make autoloads is running

in the lisp directory, the bootstrap emacs crashes (segfault) randomly.

It crashes at a different lisp file each time and I even managed to make

it get all the way through by doing:



while ! make EMACS=../src/bootstrap-emacs compile; do echo 'try

again!'; done



and waiting an hour!



I then had further problems so I bootstrapped the code on a different

(non-solaris) machine.



Now I am getting problems while compiling the quail directory.



I have done a heck of a lot of googling to no avail and before I dig

further into the code I am wondering if anyone here can give me some

tips.



Cheers,



Mark Aufflick.

Are you using CFLAGS that include one of -fast or -xarch=FOO
where FOO enables 64-bit ELF binaries?

I've been building cvs-emacs on Solaris 10 amd64 and sparc, but
only as a 32-bit binary and without -fast.  Enabling either -fast
(on any architecture) or -xarch={amd64,v9a} results in random
crashes here too.

I'm using gcc, so it would be -mcpu=v9 to force a 64 bit compile. To
check I did:

$ find . -name 'Makefile' |xargs egrep 'v9|mcpu|xarch|v9|fast'

which only matched a few lines relating to make bootfast.

And sure enough:

$ file emacs-22.0.50.1
emacs-22.0.50.1:        ELF 32-bit MSB executable SPARC Version 1,
dynamically linked, not stripped

So that's not it. But it got me hoping!

Cheers,

Mark.

I've been building without HAVE_POSIX_MEMALIGN too, since a while
back, until I track down why using posix_memalign() has problems
on FreeBSD/amd64.

Can you try running `./configure' as usual, and then manually
setting HAVE_POSIX_MEMALIGN to:

    /* #undef HAVE_POSIX_MEMALIGN */

in src/config.h before running ``make bootstrap''?

Stefan Monnier is probably the best person to track this down,
before I manage to learn enough about memory allocation in Emacs,
so if you find that disabling posix_memalign() fixes the build
for you, please let Stefan know (he's already a subscriber to the
list, so Cc:'ing him may be unnecessary).

No luck there either. config.h is auto configured exactly as you show.

I tried explicitly defining it as 1 and also undef-ing it (with a make
clean in between each). With it undefined, I get segfaults. With it
defined, I get the following:

Undefined                       first referenced
 symbol                             in file
posix_memalign                      alloc.o
ld: fatal: Symbol referencing errors. No output written to temacs


Seems solaris doesn't have posix_memalign anyway?

Probably not.  I build snapshot on Linux, FreeBSD and Solaris,
so I may have gotten these mixed up a bit.

This helps you not one jot, but for the record I just now checked a
fresh copy out of cvs on SunOS 5.8, ran `configure' (no args) and
`make bootstrap', and It Just Worked.

For the record Glen, are you using gcc or Sun cc ?

Well, I'll share the details of my compilation if you share yours... ;)

The first time, configure found gcc (3.2.3) and used it by default. I
just now tried again with "configure --without-gcc". This used "cc:
Sun WorkShop 6 update 1 C 5.2 2000/09/11". This also compiled (and
ran) fine, although there are > 1000 warnings of the form:

warning: integer overflow detected: op "<<"
warning: end-of-loop code not reached
warning: argument #1 is incompatible with prototype

I hope that someone on the list can help you debug this, but if you
have encountered a system-dependent problem, it is basically up to you
(and others who use Solaris) to fix it.
