SIGFPE is a synchornous signal and Windows will raise it if proper flag is
set (check out the example program):

But seems we didn't use the above method. Instead, we use the same
methodology as other asynchrounous signals. My question is: (1) can windows
really raise SIGFPE in our setting && (2) can we really catch it in windows?
