[bug #15818] SEGV in hash set code

[Thomas Bleher]

Follow-up Comment #1, bug #15818 (project make):

Not sure if this is the same bug, but the backtraces seem similar.
I use make CVS as of today (2006-02-21), Ubuntu Dapper (development version
of Ubuntu).

I'm trying to build SELinux refpolicy, my current source is available as
http://www.cip.ifi.lmu.de/~bleher/refpolicy-segfault.tar.gz.
Whenever I call "make -C build-tree/refpolicy NAME=refpolicy-strict
TYPE=strict-mcs DISTRO=debian DIRECT_INITRC=y MONOLITHIC=n all" on this exact
tree make immediately segfaults.

Backtrace from gdb:

I hope this is helpful.
