This needs a regression test, both to check that this fix indeed fixes the reported regression, and to make sure it doesn't regress in the future.

#140277 has -Z remap-path-scope=all --remap-path-prefix + involvement of the zerocopy macro, that's probably necessary for any smaller reproducer from that report

EDIT: a reproducer #140277 (comment), but try to trim it down further for the regression test.
