A backtrace of the segfault under i686-apple-darwin10 for gcc trunk is...

We don't seem to have any significant failures in the libjava testsuite for
i686-apple-darwin9/10 or x86_64-apple-darwin9/10 builds of gcc 4.4.2 or trunk
though. This problem seems unique to gcj and it is unclear if gcj is well
tested in the libjava testsuite.
