I keep running into this kind of problem in svn revision 1520.
hol.builder: gc_mark_phase.cpp:433: virtual void
MTGCProcessMarkPointers::ScanAddressesInObject(PolyObject*, POLYUNSIGNED): Assertion `gMem.SpaceForAddress(wordAt.AsCodePtr()) != 0' failed. Aborted
I'm guessing it's a known problem in unstable, but if not I'd be happy to provide more information as necessary. If it is known, is it likely to be fixed in svn soon?
Thanks, Ramana
