[Mono-dev] Mono SVN trunk assert failure in class.c:4021 while building Mono

[Tom Philpot]

Trying to build mono/ and mcs/ from SVN r149419 on Mac OS X 10.6 I get an assertion failure in 
class.c:4021 at which point Mono consumes about 75% of one core and must be kill -9'd

Compilation succeeded - 31 warning(s)
Assembly ../../class/lib/net_2_0/System.Core.dll signed.

ERROR:class.c:4021:initialize_object_slots: assertion failed: (finalize_slot > 0)

Note that r149400 doesn't have this issue.
