Upon Egor's suggestion, I have changed the subject line for the JIRA
and email thread.

I am currently working to finish Egor Pasko's re-implementation of
ABCD, and as a result I like to build vm.jitrino in debug mode (so
that I can use asserts). However, building vm.jitrino in debug
mode breaks DRLVM. I've created 2 JIRAs that reflect this
HARMONY-2805 and HARMONY-2804.
This raises a question in my mind. Is anyone testing DRLVM built
fully in debug mode? The default Cruise Control setup does not do
this and I find that troubling.

Subject: [jira] Created: (HARMONY-2805) VM segfault
VM segfault
-----------
Key: HARMONY-2805
URL: http://issues.apache.org/jira/browse/
HARMONY-2805
Project: Harmony
Issue Type: Bug
Components: DRLVM
Environment: RHEL 4 update 4, gcc 3.4.6, core2 (i386)
Reporter: Naveen Neelakantam
Priority: Blocker
If I build vm.jitrino in debug mode, the VM segfaults on any Java
app that runs for a non-trivial amount of time.
The bug also manifests iteself if you type:
java -Xem:server_static -showversion
