It's ABI-sensitive, but if a language or runtime decides to pass arguments in a heap location or something that's not the standard ABI, it won't work (i.e. debuginfo isn't used).

That makes is super-fragile though. GCC does a lot of optimizations on static functions that break x86 ABI (IPA-RA for example).
