As noted in the PR, GCC will segfault if a file name is first seen in a linemarker directive, and then later seen in a normal #include. This is because the fake include process adds the file to the cache with a null PATH member. The normal #include finds this file in the cache and then attempts to use the null PATH. Resolve by adding the file to the cache with a unique starting directory, so that the fake entry will only be found by a subsequent fake include, not by a real one. libcpp/ChangeLog: PR preprocessor/61474 * files.cc (_cpp_find_file): Set DONT_READ to TRUE for fake include files. (_cpp_fake_include): Pass a unique cpp_dir* address so the fake file will not be found when looked up for real. gcc/testsuite/ChangeLog: PR preprocessor/61474 * c-c++-common/cpp/pr61474-2.h: New test. * c-c++-common/cpp/pr61474.c: New test. * c-c++-common/cpp/pr61474.h: New test. |

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.
