Nah.  Theoretically possible, but I've never heard of it actually
effecting real code.  Other compiler/OS bugs - or cosmic rays effecting
your memory are much more likely to bite you.

GCJ uses the Boehm conservative collector.  Using a precise
collector with code generated by an optimizing compiler is
difficult.
