[Windows] File gets reduced to emptiness

[theodelrieu]

Hello,

I don't really know how to title it, but here is my problem:

I'm trying to reduce a Visual Studio 2019 ICE on Windows 10. After battling a bit to make creduce run on Windows, I've managed to start reducing the file, but it almost instantly reduces to 0 bytes.

The interestingness script does return 1 appropriately, so I don't have a clue about what's happening, here is the end of the log (full log attached with script + .cpp file):

===< pass_lines :: 0 >===

The file being reduced has reached zero size; our work here is done.
