Just tried it, same thing happens.

I'll try to make a better test case, but in this case, the bug happens deep in
the startup of a custom runtime that touches many files and sets up its own
version of stdio. I'll probably just amalgamate all of the required files
together. I know the policy, but the URL really is the best way to reproduce
easily.
