I see.
The LLVM - D compiler guys (LDC) seem to have exception handling
working properly in their linux version, so apparently that part of
LLVM works.

Well, the LLVM-based D compiler is mostly working on Linux now, if
you're interested. ;-)

Yeh, ok.  But development on core LLVM is not /all/ done by Apple,
right?  There must be a few who are interested in making LLVM a great
cross-platform compiler infrastructure in addition to being a great
tool for Apple.

Thanks for the useful info.
