Details:
I updated to r29256 and nothing runs since NSAutoReleasePool creates a
maptable and hence causes this problem.
Reverting back and instead use:
@class NSConcreteMapTable;
....
concreteClass = [NSConcreteMapTable class];
in NSMapTable.m works.
I am not using clang.
GDB Backtrace:
Program received signal SIGSEGV, Segmentation fault.
