The latest Solaris 11.4/x86 update uncovered a libsanitizer bug that caused one test to FAIL for 32-bit: +FAIL: c-c++-common/asan/null-deref-1.c -O0 output pattern test +FAIL: c-c++-common/asan/null-deref-1.c -O1 output pattern test +FAIL: c-c++-common/asan/null-deref-1.c -O2 output pattern test +FAIL: c-c++-common/asan/null-deref-1.c -O2 -flto output pattern test +FAIL: c-c++-common/asan/null-deref-1.c -O2 -flto -flto-partition=none output pattern test +FAIL: c-c++-common/asan/null-deref-1.c -O3 -g output pattern test +FAIL: c-c++-common/asan/null-deref-1.c -Os output pattern test I've identified the problem and the fix has just landed in upstream llvm-project: https://reviews.llvm.org/D83664 Tested on i386-pc-solaris2.11 and x86_64-pc-linux.gnu. libsanitizer: * sanitizer_common/sanitizer_linux.cpp: Cherry-pick llvm-project revision f0e9b76c3500496f8f3ea7abe6f4bf801e3b41e7.
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.
