 Could you send us a stack trace?  Be sure to CC gcc-gnats, so that the

When executing a gcj compiled program that writes
many objects to a FileOutputStream through ObjectOutputStream,
a segmentation fault occurs.

I can provide a source tree for the relevant code and instructions
on how to reproduce.  A bit lengthy here.  I'll try to come
up with a simpler test case as well.  I also have strace
output if this would be helpful
