When running pack200 on a test jar the VM segmentation faults with no
reason, and there is no hs_err*.log. Tried several tricks but no dice.
It appears the compilation thread seems to have gone into an endless 
loop. Tested with option -Xint and it works correctly.


Here is the scenario
sqe-jpi-06 /tmp> /.automount/sqesvr-nfs/root/global/nfs/deployment2/karim/JDK/amd64-linux/j2sdk1.5.0/bin/java -XX:+UnlockDiagnosticVMOptions -XX:+LogVMOutput javax.pack.Driver -pack -debug.verbose=0 -pack.effort=4 /tmp/foo.pack golden2.jar
Segmentation fault
sqe-jpi-06 /tmp> cat hotspot.log 
sqe-jpi-06 /tmp> ls -l hotspot.log
-rw-rw-r--    1 ksrini   green           0 2003-12-05 18:18 hotspot.log
sqe-jpi-06 /tmp> /.automount/sqesvr-nfs/root/global/nfs/deployment2/karim/JDK/amd64-linux/j2sdk1.5.0/bin/java -version
java version "1.5.0-internal"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-internal-b99)
Java HotSpot(TM) 64-Bit Server VM (build 20031121214924.jcoomes.baseline, mixed mode)

With b30 everything is fine.
sqe-jpi-06 /tmp> /tmp/j2re1.5.0/bin/java -version
java version "1.5.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta-b30)

The above worked fine.....

The stack trace showing the compilation thread the last 20.
