All targets are clean except x-cortex-a15 with the usual thread-related issues. However, there is one fail in asan tests, which may or may not be transcient:
-PASS: g++.dg/asan/deep-thread-stack-1.C -O0 output pattern test, ERROR: AddressSanitizer: heap-use-after-free.*(
+FAIL: g++.dg/asan/deep-thread-stack-1.C -O0 output pattern test, is qemu-arm: /build/buildd/qemu-linaro-1.0.50-2012.03/user-exec.c:100: handle_cpu_signal: Assertion `({ unsigned long __guest = (unsigned long)(address) - guest_base; (__guest < (1ul << 32)) && (!reserved_va || (__guest < reserved_va)); })' failed.

Re-spawned xcortexa15 build to make sure it is transcient.

review: Needs Information

After re-spawn, the error in asan has disappeared.
