When doing something like path completion on a directory, then hitting ^C when it says "Display all ... possibilities? (y or n)", or when ^C is entered while the readline completer is building the list of available matches, some or more of the results are leaked.

This is particularly prominent on large directories as I've seen multiple instances of bash eat up over 1GB in resident memory.

This is using both the FreeBSD port version and a git master version I handrolled to try and isolate the issue.

I thought the issue was that closedir wasn't being called in all error cases, because that's there are cookies involved in FreeBSD libc that cleanup after telldir is run, but that doesn't appear to be the sole culprit.

I'm in the process of writing up a repro script which will work on FreeBSD, Linux, and OSX.
