Hi guys,

I'm experiencing "random" sh core-dumps while building ports. During
these core-dumps, sh is usually invoked by libtool.

The system is

FreeBSD atari.bfh.ch 8.0-CURRENT FreeBSD 8.0-CURRENT #0: Tue Jun 17
01:31:25 UTC 2008 root@atari.bfh.ch:/usr/obj/usr/src/sys/ATARI sparc64

running a GENERIC-(WITNESS+INVARIANTS) kernel.

The directory on my webserver [1] contains:
- - the binary
- - the dumped core
- - a backtrace from GDB
- - a listing of the frame where the error occurs

The problem seems to be inside dowait() [jobs.c:912-1009]. Especially
the lines 927-939 seem to be of interest.

Unfortunately, I have no clue of sh's internals, so any hint is welcome!

Thanks,
