Hi Christian, Andy's already covered the major points, but you could consider filing a bug at http://llvm.org/bugs too, especially if you've got a small test-case that demonstrates the issue. Exception handling hasn't been a priority in the past, but as more people adopt LLVM's JIT APIs I suspect it will get more attention, and bug reports will help us figure out what needs doing.
