I remember having some kind of C programming bug where output filenames got scrambled (string memory error probably). And output files in the same folder as the source code.

That seems innocuous, but remember then some of the output files might have the character "?" or even "*". So imagine trying to remove these files and going an asterisk too far. All gone!
