Segmentation fault isn't exactly an exception that you can catch. It
usually means something has gone horribly wrong, like dereferencing
invalid pointer, trying to access memory out of process's range. Since
if you run out of memory Python simply raises MemoryError exception,
which you can catch. So that is not the case for segmentation fault.
