Subject Re: [drlvm][jit] DRLVM segfault with Jitrino built in debug mode (was Re: [jira] Created: (HARMONY-2805) VM segfault)
Date Mon, 25 Dec 2006 09:40:21 GMT
I've got the same recently.

The problem (As I understand) is in STL std::sprt method which works 
incorrectly when gcc is of 3.3.3 version


Mikhail Fursov will, probably, provides some details.
