I don't think this is the correct fix. What seems to be happening here is that we are trying to compute the physname for a type that is a pointer to a member function of an unnamed structure type. Because it is unnamed, c_type_print_base falls through to printing the body of the structure, instead of its name. This then crashes. Maybe NULL checks in is_constructor_name and is_destructor_name would be ok; though I am not sure. But even if those were there we would still be seeing very weird results here. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
