Sorry to trouble you with this. It was my own memory corruption problem. I accidentally allocated the LLVM Module in a memory segment type that is known to be buggy. Using the std::operator new makes the problem go away. Oops.<BR>

_SORRY_<BR>

Nothing has really changed in this part of the compiler for a long time,
and I don't think we are abusing std::map's here. Is it possible that
part of your tree is out of sync with the rest of it or something? Maybe
make clean would help?
