It breaks bootstrap on x86_64-apple-darwin10:

'__interceptor___cxa_throw' was not declared in this scope
__interceptor___cxa_throw, REAL(__cxa_throw), __cxa_throw);
^
At global scope:
cc1plus: warning: unrecognized command line option "-Wno-c99-extensions"
[enabled by default]
Commenting the lines
Printf("__asan's __cxa_throw %p; REAL(__cxa_throw) %p PLAIN %p\n",
__interceptor___cxa_throw, REAL(__cxa_throw), __cxa_throw);
in libsanitizer/asan/asan_interceptors.cc, allows boostrap to complete.
TIA
