There was a problem hiding this comment.
Maybe comment on the purpose of these...
fgets may (and certainly does when successful) change the contents of the buffer passed in. Building a regression test showed further deficiences in the stdio library model: 1) MacOS uses _fdopen; 2) fclose uses free from stdlib.h.
Licensing: I had contributed these myself to the SV-COMP benchmarks.

Even though this includes minor bug fixes I'd rather consider these enhancements - not adding a "bugfix" label.
