   Thank you--this does affect the behavior.  I reverted the change made in
locks.c revision 1.48 (only one line was changed in that revision) and the
first regression test that I posted here (the class called BigIntTest) now works.

   Unfortunately, it doesn't fix the second testcase that I posted here (the
one called BigIntTest2).  That still fails at the same place (when numbers get
above 2^16,000,000; I tried increasing heap and stack space with no effect)
with a segmentation fault.

   Reverting this change may be an improvement, but I don't know of any
side-effects of making this change.  Is there anything else I can try to get
the second testcase to work?  (I'm aching to get this working; Kaffe with GMP
is so much faster than Sun's VM for this that I really want to announce it as
a good alternative.)
