Failure of Travis on Windows due to Unix style paths about image-png HOT 3 CLOSED

Somehow the path being inserted into ref_results has backslashes converted to to slashes.

This is the string which gets inserted into ref_results: ""tests/pngsuite/basi3p04.png""
This is the string which is expected to be in ref_results: ""tests\\pngsuite\\basi3p04.png""

Edit: results.txt has Unix style forward slash directory separators which mismatch Window's backslashes.

There's also the odd issue where the backslashes get escaped and reinterpreted as double backslashes

Oh, so the order (and thus the first we panic on) is just different because of non-deterministic hashing operation? That makes sense, actually.

It's reproducible on my windows box, so I'm having a look at this atm
