Mauve harness failure on s390

I see this with both gcj 3.3 20030130 and gcj 3.4 200301030 on
s390-ibm-linux and s390x-ibm-linux.
What I'm wondering is why this is apparently platform-dependent;
I'd have thought the compilation to bytecode would be independent
of the platform, and likewise the question whether any given
bytecode sequence contains unreachable code or not ...
Any suggestions how to debug such problems? Is there something
like a bytecode disassembler / verifier / analyser tool?
Thanks,
Ulrich
