I had the same *&#! problem. I include a little section from my config.h
file (emacs/src/config.h) which took care of it:

 /* SunOS 4.1 localtime scribbles on the ninth byte.  
  * This includes a workaround piece of code in 
  * malloc.c
  */
 #define SUNOS_LOCALTIME_BUG

Then in your malloc.c at about line 479 you need:
 #ifdef SUNOS_LOCALTIME_BUG
    /* SunOS 4.1 localtime scribbles on the ninth byte.  */
    nbytes = (n + ((sizeof *p + 15) & ~15) + EXTRA + 15) & ~15;
 #else
     nbytes = (n + ((sizeof *p + 7) & ~7) + EXTRA + 7) & ~7;
 #endif
...instead of:

   nbytes = (n + ((sizeof *p + 7) & ~7) + EXTRA + 7) & ~7;

Good Luck.
