Similar to the memcmp patch, this is undefined behaviour, it doesn't 
make sense to add a test for this or to explicitly modify memset to 
guarantee a segfault if it has a performance impact.

Patch 2/3 looks like it could be included on its own since the new tests 
don't seem to test undefined behaviour.
