--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note some extern "C" functions in glibc support throwing from the call back.

The same can be true from noexcept functions. Where they catch all exceptions
from the call back function. 

 So this is more complex than what you are asking for.
