I don't know windows exception handling well, but if it's...

Windows: How to catch C++ exceptions in runtime-compiled code?
...ing the same code at runtime and loading it with the ORC libraries, every throw results in an unhandled exception. The point of interest seems to be the throw handler for C++ exceptions (throw.cpp):
__declspec(noreturn) extern "C" void __stdcall
_CxxThrowException(void* pExceptionObject, _ThrowInfo* pThrowInfo)
{

ThisException.ExceptionFlags,
ThisException.NumberParameters,
(PULONG_PTR)&ThisException.params );
}

Clang/LLVM JIT - When to use "registerEHFrames()"
Hello Stefan,
I'm happy someone replied to my problem! Many thanks! To be honest... I
didn't understood much of your mail. I'm a beginner with the JIT - so I
will explain what I've done.
To manage the memory and resolve symbols, I'm using my own Resolver-Class,
which overloads the allocation and the findSymbol functions. I've noticed
today, that the
