GCJ application runs not too bad with shared libs, but crashes with static libs - seems to be in _Jv_MonitorEnter

I'm wondering if static memory isn't getting clobbered somehow by your
program. Clue #1 is that shared builds don't fail. Clue #2 is the
failure in is_mp, which ought have been initialized by then. Clue #3 is
the SIGSEGV in sscanf, as if a format string had been overwritten.
Can you put a breakpoint on is_mp() and prove it is only called once?
