There isn't a portable way to obtain the address of a label in C or its descendants.

I see you're on Windows with MSVC - it often helps to be explicit about platform (and, in this case, compiler) versions. There might be a specific trick, but there probably isn't.

Maybe you're reverse-engineering some assembler code and need to incorporate more of the code in assembler.
