emacs dumps core on exit under solaris 2.8

emacs dumps core on exit under solaris 2.8

Hello,

I am trying to compile emacs 21.2 on a solaris 2.8 computer, using gcc
3.2.

During the compilation process, the just built emacs is used to do
several thing (for example loading blessmail). Everything seem to work
fine except that upon exit, emacs dumps core. In this particular place,
this stops the make process. I noticed several prior crashes in the
previous lines.

I even reproduced this with the simple command :

  ./emacs -q -batch

After having read the MACHINE file and the PROBLEMS files, I have tried
to configure using --with-xim=no, but I still have this problem. The
post-mortem debugging session attached shows there is a segmentation
violation, but there is no information on where this comes from.

Here are some informations :

uname -a :
SunOS cepheus 5.8 Generic_108528-11 sun4u sparc SUNW,Ultra-5_10

emacs configured with :
  --prefix=/usr/local --with-x-toolkit=motif
  --infodir=/usr/local/info --with-sound=no
  --with-xim=no

compiler gcc 3.2

                                                       Luc

Re: emacs dumps core on exit under solaris 2.8

It looks like this is a matter of an error in the cleanup routine of
some library.  In cases like these, often the innermost stack frame
before the signal is not visible.  That stack frame might tell us
which library has the problem.

If you put a breakpoint at the start of __do_global_dtors_aux and then
step with si to see what functions it calls, you may be able to tell
which library it is.

Thanks a lot.

I tried this, but it seems the segmentation violation comes from within
__do_global_dtors_aux itself. You will find the gdb session attached,
with display/i $pc on, in order to get the instruction at each step. The
o1 register is null at this time, so it explains the violation. I don't
know what is in this register and why it is null.

So I have tried to remove some libraries using the configure option. All
works well when I remove libpng with the --without-png flag.

I tried to recompile both zlib 1.1.4 and libpng 1.2.5, just to make sure
everything was compiled with the same version of the gcc compiler, but
still had problems.

So I have dropped png support for now, and compile emacs using
--with-xim=no and --without-png.

Thanks for your help.
