Rollup merge of #146907 - cyrgani:146537-test, r=nnethercote
add regression test for issue 146537 Adds a test based on the reduction in https://github.com/rust-lang/rust/issues/146537#issuecomment-3289438439. This was already fixed in rust-lang/rust#142882 before the issue was even reported, but no test for it was added yet.
