--- Comment #7 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Andrew Pinski from comment #6) > Reduced testcase for that: > void f(void); > void f(void) throw(int); > void f(void) throw(int); > > Noexcept has the same issue: > void g(void); > void g(void) noexcept; > void g(void) noexcept; It is even worse when the first declaration is in a system header file, the second declaration does not cause an error during merging but then we lose the throw/noexcept but have the line number of the second decl so when we go and merge in the third decl, we do the error message that way.
