This may be related to 1238673, but for our testing purposes it's important enough to note on it's own. /usr/green2/sqe/automatic/other/gctests/gctest03 reliably causes the x86 platform to dump core. Combinations of the gctests also do this, and on one occasion rendered the entire system useless, but that is a severe stress test. This test should be able to run on it's own indefinitely; it does not.

The environment that produced this file is the April 8 x86 build from /usr/local/java/x86.
