I haven't looked at the code, but I suspect it is so that it can
intercept such faults (eg. null pointer dereferences) and translate them
into test failures.

_set_se_translator can be used to automatically convert SEH exceptions
into a specific C++ exception (which is better than using catch(...)),
but /EHa must be enabled on the code where the exception is thrown in
order to get an accurate location.
