Error if preamble changes

[Enivex]

I've gotten the compilation part working, and it'll recompile if I change the file (Compile time down about 30%, thanks!). Except if I change the preamble, then it errors out:

Windows is weird. I'll investigate later.

Sorry for giving you headaches!

(everything is in a single tex file, so the \input part isn't relevant)

[user202729]

Looks like it was a real resource leak. Hopefully fixed (and add a test for it). Didn't reboot to Windows to test though.

Unfortunately I'm still getting

(At least the error seems shorter this time)

Will reboot to Windows and test later. It's night here already.
