I would check that.  It didn't affect ABI in C++11/14, but I am not so
sure about C++17.  According to
http://en.cppreference.com/w/cpp/language/noexcept_spec,
in C++17 "The noexcept-specification is a part of the function type and
may appear as part of any function declarator."  If it is part of the
type then it might feature in name mangling, so this is worth checking
with the compiler writers.
