The bug manifests itself when a cog code compaction occurs soon after an MNU PIC has been created and the symptom is a fatal crash. So a) it is very difficult to reproduce and b) there would be no neat test failure, there would be a core dump. Yes this is useful for a Jenkins context, but in general I think it better to test things like this with heavy stress tests (and general community usage) rather than trying to produce a specific test. > Stef > > > > ...in http://www.mirandabanda.org/files/Cog/VM/VM.r2495/.
