Ah, that's very helpful.  Thank you!

Based on that pointer, I've dug into the mod_facl code more closely, and
indeed saw the memory leaks.  I've created a pull request which fixes
the issue:

  https://github.com/proftpd/proftpd/pull/357

And I've verified the fix using Valgrind.  While there, I also fixed the
handling of the FACLEngine directive to do what you'd want/expect here.

I'll be merging this PR shortly, and backporting it to the 1.3.5 branch.

Cheers,
TJ
