Summary: Fix stringop-truncation warnings casused by gcc. The newer gcc(gcc-8 or higher) would warn for calls to bounded string manipulation functions such as 'strncpy' that may either truncate the copied string or leave the destination unchanged.
The reason is that -fsanitize=address might simply incompatible with -Wstringop-truncation. This patch disables stringop-truncation warning when asan enabled, also disables the defining of _FORTIFY_SOURCE in fastdebug builds for some potential risks. ------------- Commit messages: - 8252407: Build failure with gcc-8+ and asan.
