Crash of Emacs 22.1

[Jochen Luebbers]

Hello,

unfortunately my emacs crashed. I was not used to such things by emacs,
until I got this GNU Emacs 21.3.1 from RHEL 4.

At the behest of this news groupe I updated to GNU Emacs 22.1.1 at the
31th of october and every thins seems to be fine.

But today I got ie again. It was just, when I selected
"Postscript Print Buffer (B+W)" from the menu. (The printout was not
started.)

But this time I got a usable core-dump, I thought. But am I right?

Look at this, it seems to be the interessting part of the dump:

#18 <signal handler called>
#19 0x0812d0a9 in mem_delete (z=Variable "z" is not available.
) at alloc.c:3940
#20 0x0812d30e in lisp_free (block=0x9621708) at alloc.c:893
#21 0x08131386 in Fgarbage_collect () at alloc.c:6259
#22 0x0816c992 in Fbyte_code (bytestr=136141291, vector=136141308, maxdepth=48)
    at bytecode.c:724

Obviously the crash happened during a garbage collection. But at line
3940 of file alloc.c there is not routine "mem_delete".
There is "mem_delete_fixup"...

So it's no surprise when gdb says: z=Variable "z" is not available.

Seeking for advice: How can I help to fix things here?

Regards
    Jochen
