From Naveen Neelakantam <neela...@uiuc.edu>
Subject Fwd: [jira] Created: (HARMONY-2805) VM segfault
Date Tue, 19 Dec 2006 21:05:12 GMT
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.

Naveen
