Summary: Key manager, EH frames, JIT and Mac OS X 10.5.7 (llvm
2.5)

There seems to be an issue in LLVM v2.5 with proper operation of exceptions
within an application once the JIT is created (I know, I know, the JIT does not
do exceptions yet). My app crashes each time it throws an exception after it
first initializes the JIT. I noticed that in JIT.cpp in the trunk that the key
manager is not used to register EH frames (see r69090). This patch appears to
be active for Mac OS X 10.5 and beyond -- the comment in the log suggests 10.6,
but I encounter the issue on 10.5.7. I was unable to make HowToUseJIT
reproduce the problem, but the existence of r69090 suggests this is a known
issue. Disabling the key manager call appears to make everything work as
expected.
