tup internal error: create_ignored_file() didn't get a final pel pointer for file

This seems to be a tup internal error, rather than just bad Tupfile etc.

I'm hitting this on both WSL 2 (Ubuntu x86_64) and on macOS 12.4 (arm64). I don't have any other platforms to test on.

WSL 2 version:

macOS 12.4 version:

tup error: Missing input dependency - a file was read from, and was not specified as an input link for the command. This is an issue because the file was created from another command, and without the input link the commands may execute out of order. You should add this file as an input, since it is possible this could randomly break in the future.
