Perhaps not. Even one collection may not be enough to fail.
I don't have any small testcases that demonstrate the problem reliably,
not even GCBench. But I've seen a problem on Alpha consistent with what
Hans describes.

Nothing in the source tree, no. But you can vary the initial heap size,
and a large heap can mask the problem by deferring a collection. I've
done just that to help diagnose GC problems.
