Yep, it would be an incompatible ABI. I don't really know how common this in practice -- but there was a comment warning about this in the old ufunc sources, so I wanted to be wary... I don't think there's a significant downside in having thin wrappers around the pointer functions. Googling a bit reveals at least some issues that have cropped up in gcc: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36834 (MSVC vs. gcc) http://gcc.gnu.org/bugzilla/show_bug.cgi?id=9506 (bug on freebsd) I'd imagine the situation vs. compilers is here a bit similar to C++ ABIs and sounds like it's a less tested corner of the calling conventions. No idea whether this matters in practice, but at least the above MSVC vs. gcc issue sounds like it might bite.
