--- Comment #3 from emsr at gcc dot gnu.org --- Created attachment 33949 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=33949&action=edit Quick patch. I'm not on a box I can easily build and test. Here is a quick one leaving aside the question of whether this cb needs defined in other contests. At least let's not not invoke non-existent cb.
