The patch for 96391 changed linemap_compare_locations to give up on comparing locations from macro expansions if we don't have column information. But in this testcase, the BOILERPLATE macro is multiple lines long, so we do want to compare locations within the macro. So this patch moves the LINE_MAP_MAX_LOCATION_WITH_COLS check inside the block, to use it for failing gracefully. PR c++/100796 PR preprocessor/96391 libcpp/ChangeLog: * line-map.c (linemap_compare_locations): Only use comparison with LINE_MAP_MAX_LOCATION_WITH_COLS to avoid abort. gcc/testsuite/ChangeLog: * g++.dg/plugin/location-overflow-test-pr100796.c: New test. * g++.dg/plugin/plugin.exp: Run it. |

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
