Re: 3.2 bootstrap failure in libjava on sparcv9-sun-solaris2.8

[Brad Lucier <lucier at math dot purdue dot edu>]

OK, mainline still doesn't bootstrap today, and I decided to try to narrow
down where the problem is, so I fired up gdb, but the program exited
with an error status rather than actually segfaulting, so I couldn't see
where it was failing.

How is one supposed to debug this?
