Re: Intercepting C++ throws

Willard,

That message is for the gcc 2.95 implementation of throw. For gcc3.1 the immediate call is __cxa_throw. But that is not so useful, because you will get a different copy of this in each shared library. Looks like this and the rethrow funnel through _Unwind_RaiseException, which is in libSystem.dylib. So breaking on _Unwind_RaiseException is probably the best choice.

Hope this helps...

Jim

Any suggestions? I'm not eager to step through the massive third-party library (OpenCASCADE) to find the site of the throw.
