Oops. I'll fix that one. (We should be using 'jlong'
everywhere... though that causes some problems elsewhere...). Your
fix should be good enough for the Alpha version.

Could you get another GDB backtrace from the core file with the
-vmdebug GCDIAG argument? Perhaps it blew up earlier with the
GC "diagnostics" turned on.

Nothing odd reported here. Good.

Well, if you want to try tracking this down further, you might avoid
the JIT entirely. Re-configure with '--with-engine=intrp'. See if
that builds and passes the checks. Hopefully someone can chime in
with actual experience with Kaffe on an Alpha...
Also, if you're interested in working on this, you should probably get
the most recent CVS snapshot (see http://www.kaffe.org/CVS.html).

Yep, looks good to me too. As long as there isn't anything funny in
Hmm... looking through the logs in config/alpha I messages like:
Follow ``Calling Standard for Alpha Systems'' and add exceptions
Dec OSF/1 with libexc.
@@@ Be careful, it's not yet working. @@@
Hopefully, "working" isn't too far off.

Does the name `Pavlov' ring a bell?
