I'm building the following Buildroot Custom toolchain config and noticing a libsanitizer failure. ../../../../libsanitizer/asan/asan_linux.cc: In function âbool __asan::AsanInterceptsSignal(int)â: ../../../../libsanitizer/asan/asan_linux.cc:222:20: error: âSIGSEGVâ was not declared in this scope return signum == SIGSEGV && common_flags()->handle_segv; ^ make[6]: *** [asan_linux.lo] Error 1 make[5]: *** [all-recursive] Error 1 make[4]: *** [all] Error 2 make[3]: *** [all-target-libsanitizer] Error 2 make[2]: *** [all] Error 2 make[1]: *** [/accts/mlweber1/target/build/host-gcc-final-5.4.0/.stamp_built] Error 2 make: *** [_all] Error 2 Config to reproduce: BR2_powerpc=y BR2_powerpc_e500mc=y BR2_TOOLCHAIN_BUILDROOT_GLIBC=y BR2_KERNEL_HEADERS_VERSION=y BR2_DEFAULT_KERNEL_VERSION="3.12.37" BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_3_12=y BR2_GCC_VERSION_5_X=y BR2_TOOLCHAIN_BUILDROOT_CXX=y BR2_GCC_ENABLE_LTO=y The resolution looks to be https://www.mail-archive.com/gcc-patches@gcc.gnu.org/msg159613.html I'll get a patch tested and I can confirm so far that the issue goes away in GCC6 but GCC5.4 has the bug.
