Aaron Gyes	b00b1af152	Improve realpath error reporting, fix a crasher ... realpath() will return NULL and sets errno if it fails. We asserted that realpath(".") does not fail. We also didn't really check that it was successful. Made sure we'll get a perror telling us about what went wrong if something like this happens again. Updated tests and added test case Fixes #5351	2018-11-18 09:35:58 -08:00
