System: NetBSD rumpole.bohemians.lexington.ky.us 1.4 NetBSD 1.4 (GENERIC_SCSI3) #0: Sun May 9 04:05:20 MEST 1999 pk@flambard:/usr/src/sys/arch/sparc/compile/GENERIC_SCSI3 sparc


>Description:
When running the following command inside of swig's package, the system
crashes:

c++ -I../Include -O2 -DSWIG_LIB='"/usr/pkg/lib/swig_lib"' -DSWIG_CC='"c++"'  -DSTDC_HEADERS=1 -DHAVE_ALLOCA=1 -DSWIG_LANG=TCL -DSWIG_DOC=ASCII parser.cxx -c -o parser.o

I can run this command with no other significant load on the system 
(all that I have running is ssh-1.2.27 and sendmail), even after a fresh
reboot, and get it to crash.  The system has 16M of memory & 150M of swap,
and it uses only ~1/3 of the swap before crashing.

This same bug appears to occur during other heavy compiles as well, although 
I cannot cause it to occur with consistency. I don't believe that it's
hardware, since the machine was working fine (including occasional heavy
compiles) when I had a 1.3-current snapshot on it. 

This crash has happened with both kernels out of the distribution set, as well
as a kernel I compiled myself.

I finally got a trace with a ddb kernel as well. It (and the only console
output at the time of the problem) is:

rumpole# extent `swap0x0000' (0x0 - 0x833f), flags = 0x0
