--- Comment #5 from Daniel Richard G. <skunk at iskunk dot org> ---
I get this same error building on an old Debian woody system:
/home/src/gcc-4.8.1/libsanitizer/sanitizer_common/sanitizer_linux.cc: In

gmake[4]: *** [sanitizer_linux.lo] Error 1
Would a fallback implementation of BlockingMutex::{Lock,Unlock}() that uses
pthread_mutex_*() be sensible here?
