--- Comment #3 from Bernd Edlinger <bernd.edlinger at hotmail dot de> --- Created attachment 39472 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=39472&action=edit possible patch Oh, yeah! Boot-strap OK. The eh-code is OK. BUT: the warning triggers a few hundred times, within the g++.dg testsuite, and all of the places look like real bugs, that deserve a warning...
