[Bug c++/29632] New: ICE on invalid code: regenerate_decl_from_template, at cp/pt.c:10969

["jkherciueh at gmx dot net" <gcc-bugzilla at gcc dot gnu dot org>]

The following crashes g++:

struct nullptr_type {

  nullptr_type ( void ) {}

  template < typename T >
  operator T* ( void ) const {
    return ( 0 );
  }

} const nullptr;

int main ( void ) {
  0 == nullptr;
}


g++ -v:
