Compiling with /opt/bin/gcj -g -fcheck-references, it still gives me
the abort instead of the signal.  I tried it with the gcj in 3.4.5,
and the program performs as normal there, without any special flags at
all.

Yeah, I do have a core file.  my gdb isn't very happy with it though. 
It says it can't find thread 1, and gives up.  If a backtrace would be
useful, I'll try to generate one though.
