Stack overflow is still synchonous. But really there is not much to be done with a stack overflow. it is hard for anything to do with both stack overflow not in malloc and one in malloc unless you know you are not in malloc. Still not a bug which is fixable easily. Still a BUG in tsan for reporting a non bug. Please report this to TSAN for reporting a non BUG. Thanks, Andrew Pinski
