[libcxx-commits] [PATCH] D122257: [libc++] Fix undefined behavior in `std::filebuf`

[Martin Storsjö via Phabricator via libcxx-commits]

mstorsjo added inline comments.


================
Comment at: libcxx/test/std/input.output/file.streams/fstreams/filebuf.assign/nonmember_swap_min.pass.cpp:12-14
+// FIXME: This test fails on Windows for some reason, but even before the swap,
+//        which is what we want to test here.
+// UNSUPPORTED: target={{.+}}-windows-{{.+}}

We should be able to get rid of them and finally close https://github.com/llvm/llvm-project/issues/32077 real soon now, I'm just waiting for a CI runner upgrade)

See D122612 for a fix for this issue.
