Hm, that makes sense. I'll give the cross-project-tests a look.

However, one general question that comes to my mind here: The addresses will probably be platform-specific. How can I deal with that? I can determine the addresses on my local (Linux amd64) platform, but how would I do the same generally? I can use `nm` to determine the address of `main` (which for the canned binary is 0x400540), but I need some offset to identify an inlined location (which is 0x40054d) for the canned binary. I probably can't generally assume that 0xd is an appropriate offset for any platform.
