[LLVMdev] Catching exceptions passed through a JIT ExecutionEngine

[Peter Zion]

Yes, I did -- it made no difference.  Should it?

Note that I have since discovered that this is not a problem on Windows -- the exception drops through as expected.

Specifically, in C++ code, inside a try/catch block, I call a JITted function, which in turn calls back into my code.  Everything works fine unless an exception is thrown; I would except the outermost try/catch(...) block to catch the exception thrown in my innermost C++ code, but instead I get the abort "terminate called after throwing an instance of 'MyException'".  I am compiling the system with g++ (on Linux and OSX); I haven't tried MSVC++.

I admit that I have only a fairly basic understanding of how exception handling is implemented in C++ but from what I've read it seems like the exception should unwind through what is, for all intents and purposes, a simple call stack...
