I've seen this problem posted a few times but if there
has been a response, I've missed it.

Symptom:emacs crashes in malloc

System: any sun (I only have Sun-3's but I've heard
        of the identical problem on Sun-4's)

	SunOS 4.1

Description:

The dumped 'xemacs' fails run, aborts at line 515 in malloc.c:
   510       /* and bomb out on the NEXT allocate of this size block */
   511       if (p -> mh_alloc != ISFREE || p -> mh_index != nunits)
   512     #ifdef rcheck
   513         botch ("block on free list clobbered");
   514     #else /* not rcheck */
>> 515         abort ();
   516     #endif /* not rcheck */
   517

stack dump:

#0  0x407d4 in kill ()

I tried removing all .elc files, undef-ing
X11 code, and compiling with both cc and gcc.
None of these measures seems to have helped.

I can duplicate the abort at the same spot by 
1) recompiling temacs with a BIG PURESIZE
2) running "./temacs -l loadup.el"
3) hit 2 esc's 
4) bottom line displays "Loading novice..."
4) temacs aborts

Has anyone else seen this problem / found a fix?
