FWIW: it's quite easy to reproduce with pkgsrc:
beagle# cd /usr/pkgsrc/x11/deforaos-panel/
beagle# make install
make[3]: "if [ -x /usr/pkg/sbin/pkg_info ]; then echo /usr/pkg/sbin; else echo 
/usr/sbin; fi" exited on a signal
sh: /pkg_admin: not found
test: 20090528: unexpected operator

and on the console:
data_abort_handler: data_aborts fsr=0x182e far=0x40062000

I suspect pkgsrc does a lot of calls of this kind, because ot doesn't always
take the same time to get the signal. But I couldn't get the build to start.

I tried running this sequence:
if [ -x /usr/pkg/sbin/pkg_info ]; then echo /usr/pkg/sbin; else echo /
usr/sbin; fi
in a shell loop, but it didn't cause the problem, so it looks like
make has something to do in the problem.

I also got:
make[3]: "" exited on a signal
as if a memory got corrupted. And also
make[2]: "../../mk/compiler/../../mk/compiler/gcc.mk" line 168: warning: "( env 
LC_ALL=C /usr/bin/gcc -v 2>&1 | /usr/bin/grep 'gcc version') 2>/dev/null || 
echo 0" exited on a signal
make: "../../mk/../../mk/bsd.prefs.mk" line 706: warning: "cd 
/usr/pkgsrc/x11/deforaos-panel/../.. && /bin/pwd" exited on a signal

Unfortunably, no core dump.

Here's a kdump related to one of these messages:

Maybe it's related to vfork ?
