--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
But that just stopped the mismatch being ignored, the real bug was adding the
NOTHROW in the first place, in r13-3381-gf036d759ecee53

The API is defined by the declarations in cxxabi.h so the definition should not
be marked noexcept.
