Your question is asking for something that isn't conceptually possible.

Try blocks are defined as dynamic constructs of the stack. A try block catches exceptions thrown by code reached dynamically, by call, from its contents.

When you create a new thread, you create a brand-new stack, that is not at all part of the dynamic context of the try block, even if the call to pthread_create is inside the try.
