Linux (kernel 2.4.17) x86, using *Both* libGCJ system classes, and IBM 1.3 JRE system classes, and class files byte-compiled with Jikes Compiler (v1.18 - 2002/11/21)

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

Additional Info:
This SegFault only happens when I try and use the IBM javax.swing classes from their jar file.  Minor bug, I'm guessing.
>How-To-Repeat:
Use gcj with IBM runtime file and with the libgcj runtime file.
