kaffe-0.9.2 SIGSEGV on openbsd2.2-x86pc

I would like to get kaffe-0.9.2 running under OpenBSD/x86pc, but seem to
be stymied by some sort of SIGSEGV caused by the Kaffe thread scheduler

Attached is a SIGSEGV received by an attached GDB.  Essentially it seems
like the current frame is trashed on entry into the reschedule call.

kaffe-0.8.4 works fine on this system, but I need Java 1.1 for my
projects.  I have compiled statically, looked over the patches on
'rufus.w3.org', and compared with the patches being distributed in the
NetBSD port.  Nothing seems to effect the SIGSEGV behavior.

Any and all help would be appreceiated, especially other individuals in
the {Free,Net,Open}BSD community who can point me to more information.


In general, if someone could post a brief summary to this list what the
status of a "next" Kaffe release might be, I would be extremely grateful. 
There seem to be more than enough patches for a kaffe-0.9.3 to go out,
especially if you wanted 'java.lang.reflect' to work.

Thanks for any and all help.
