Have you tried building with -fno-strict-aliasing? Bug#8217 is about a
crash during garbage collection that apparently disappears with
-fno-strict-aliasing, and I've been also experiencing
garbage-collection crashes in non-optimized gcc 4+ builds that seem to
be "cured" (or most likely, hidden) by that option.
