--- Comment #3 from David Malcolm <dmalcolm at gcc dot gnu.org> --- Author: dmalcolm Date: Thu Mar 17 18:27:47 2016 New Revision: 234303 URL: https://gcc.gnu.org/viewcvs?rev=234303&root=gcc&view=rev Log: PR c/70264: fix crash in compatible_locations_p with BUILTINS_LOCATION In r234088 my fix for PR c++/70105 didn't allow for the possibility that when comparing a pair of macro expansion histories that one of the macros in the history might not be located within a line-map, and PR c/70264 reports a crash due to encountering BUILTINS_LOCATION within the traversal. Fixed thusly. Successfully bootstrapped on x86_64-pc-linux-gnu; adds 4 PASS results to gcc.sum and 12 to g++.sum. gcc/ChangeLog: PR c/70264 * diagnostic-show-locus.c (compatible_locations_p): Handle the case where one or both locations aren't within a line_map. gcc/testsuite/ChangeLog: PR c/70264 * c-c++-common/pr70264.c: New test case.
