--- Comment #38 from Lawrence Velázquez <larryv at macports dot org> --- Created attachment 33464 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=33464&action=edit Corrected dirent patch Couple of things: 1) The version of Sanitizer included with GCC 4.9.1 at least, and probably earlier, has the includes in the wrong order in sanitizer_platform_limits_posix.cc: #include "sanitizer_platform.h" #if SANITIZER_LINUX || SANITIZER_MAC #include "sanitizer_internal_defs.h" #include "sanitizer_platform_limits_posix.h" #include <arpa/inet.h> #include <dirent.h> Since sanitizer_platform_limits_posix.h is included before the system headers, _DARWIN_FEATURE_64_BIT_INODE is *not* defined for the second hunk of your patch, and the 32-bit dirent is always used. However, it *is* defined for the first hunk, so CHECK_SIZE_AND_OFFSET does try to access d_seekoff (and predictably fails). The ordering is fixed in Sanitizer upstream, but it's more robust to directly include sys/cdefs.h in sanitizer_platform_limits_posix.h to avoid relying on include ordering. 2) You should report this bug upstream. http://compiler-rt.llvm.org
