Mats Kindahl 3bea4a20a4 Bug #58455 ...

Starting mysqld with defaults file without
extension cause segmentation fault

Bug occurs because fn_expand calls fn_format
with NULL as ext.

This is a backport of the patch from 5.6.

Patch solve this problem by using an empty
string as extension, and adding assertions
to fn_format that correct arguments are passed.

It also add a test tests several variations of
using non-existing defaults files.
