@codebrainz all declarations and the definition need to have the same exception specification in C++.

To quote the surprisingly lucid standard clause "If any declaration of a function has an exception-specification that is not a noexcept-specification allowing all exceptions, all declarations, including the definition and any explicit specialization, of that function shall have a compatible exception-specification."

That was the OP wasn't it?

@b4n the standard requires an extern "c" function to have a C compatible ABI, and it does not disallow noexcept so if the compiler allows noexcept then it must not change the ABI. (or the compiler has a bug)
