I thing I reported this back when I found it but in case I didn't:

emacs would quickly complain about running out of memory and core dump on 
amd64 systems on NetBSD.  Problem was tracked down to a bug in ralloc.c that 
caused a negative number intended to be an argument to sbrk() to reduce the 
break to be treated as a large positive one (because of wrong sized object 
being passed on the stack).

Below patch fixes:

- --- src/ralloc.c.orig	2001-02-20 01:19:40.000000000 +1300
+++ src/ralloc.c
@@ -328,7 +328,7 @@ static void
 relinquish ()
 {
   register heap_ptr h;
- -  int excess = 0;
+  long excess = 0;
 
   /* Add the amount of space beyond break_value
      in all heaps which have extend beyond break_value at all.  */

cheers
mark

I installed it.  (I assumed you already checked it for correctness.)

Thanks.
