Please add a test for the default behavior i.e. when -ffpe-trap is not specified. 

In general, you want to pass the minimum number of options to the driver that test the behavior that you are interested in. If you are passing `-###`, you are instructing clang to generate the command lines, but not really execute them. In this case, you may not need `-fsyntax-only`.
