   I really doubt it, though I can replace the memory and swap
machines tomorrow if I need to. It is a stock machine from Dell
with no mods.

   This machine has been dedicated to building -current SNAP's
for more than 8 months. When this machine has problems, the typical
problem is bad code getting into the system, or a corrupted
filesystem (I nolonger run any of my filesystems async for this
reason).

   fyi, this problem does replicate at the exact same location. It
appears to actually be yacc...

/usr/obj/usr/src/gnu/usr.bin/cc/cpp %ls -al
drwxr-xr-x   2 root  wheel     512 Aug 25 23:53 .
drwxr-xr-x  16 root  wheel     512 Aug 25 23:47 ..
-rw-r--r--   1 root  wheel   92936 Aug 25 23:53 cccp.o
-rw-------   1 root  wheel  147456 Aug 25 23:53 yacc.core
/usr/obj/usr/src/gnu/usr.bin/cc/cpp %file yacc.core
yacc.core: ELF 32-bit LSB core file, Intel 80386, version 1 (FreeBSD), from 'yacc'

gdb says the following:

(no debugging symbols found)...
Core was generated by `yacc'.
Program terminated with signal 11, Segmentation fault.
#0  0x8051bec in free ()

   I guess I'll try to build a debug version next...

Thanks,
John
