gcc 4.9.2 fails to build for sparc-buildroot-linux-gnu (buildroot git HEAD as of today).

In file included from ../../../../libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc:17:0:
../../../../libsanitizer/sanitizer_common/sanitizer_internal_defs.h:257:72: error: size of array ‘assertion_failed__865’ is negative
     typedef char IMPL_PASTE(assertion_failed_##_, line)[2*(int)(pred)-1]
                                                                        ^

Full log attached.

Care to provide a config?
I was able to build qemu_sparc_ss10_defconfig switching to gcc 4.9.2 just fine and it even boots.
Comment 2 Uwe Hermann 2015-03-19 15:40:03 UTC 
Yup, qemu_sparc_ss10_defconfig works for me as well. The attached config (based on a fresh checkout, "make menuconfig" and only minimal changes to the config settings) doesn't build for me though.
