thanks for that! On Jitrino debug mode.. on Linux.. I do build it regularly :) and working on it's stability, but yet, often something is broken, recent failures on Classlib tests were resolved yesterday. I believe we will enable Jitrino debug mode soon via option to 'build.sh' and by default, just wanna make the debug/release switch without forced full rebuild. On the specific issue.. Recently I met the same weird bug as you see. It is a blocker for me too, so, I am looking into it. > Naveen > > On Dec 19, 2006, at 3:05 PM, Naveen Neelakantam wrote: > > > 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).
