After the commit f67a4f50e2 "gcc: preserve CXXFLAGS_FOR_TARGET"
target CFLAGS are passed to all libraries bundled with gcc. This breaks
libsanitizer on gcc-4.9.x when building with _FILE_OFFSET_BITS=64:
error: size of array ‘assertion_failed__837’ is negative
...
libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc:837:1:
note: in expansion of macro ‘CHECK_SIZE_AND_OFFSET’
CHECK_SIZE_AND_OFFSET(dirent, d_ino);
This issue is fixed in the libsanitizer mainline and in gcc-5.x.
There's no issue with gcc-4.8.x and earlier.

Subject: [PATCH] [sanitizer] Fix build with _FILE_OFFSET_BITS=64.
|
|
|
|
Sanitizer source is not affected by _FILE_OFFSET_BITS in general,
|
|
but this one file must be built with 32-bit off_t. More details in the code.
