If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

I don’t think you need core for this test anymore.

r=me with import of libcore removed and test move from debuginfo to run-pass/fail as appropriate.

[c3st7n]

I have moved the test to the run-pass directory, set to use compiler-flags and changed from a lib to a bin - test passes.
