--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> --- Ah, so we have this_42(D)->_M_positive_sign_size = 0; _62 = operator new [] (0); (possible EH) <bb 35> [local count: 268220751]: _6 = this_42(D)->_M_positive_sign_size; _192 = MEM[(long unsigned int *)&D.281666(address-taken) + 8B]; _188 = MIN_EXPR <_6, _192>; if (_188 != 0) goto <bb 36>; [50.00%] and 'new' is now (after some "recent" fix) possibly clobbering this->_M_positive_sign_size. I suggest to save that to an automatic local, only loading it once as workaround.
