Heads up: this commit causes the STREAM project (https://github.com/jeffhammond/STREAM.git) to fail at the `checksums` subroutine (https://github.com/jeffhammond/STREAM/blob/6703f7504a38a8da96b353cadafa64d3c2d7a2d3/stream.f#L398), even when running with just a single OpenMP thread. Before opening a bug report, I'll try to build `main` with this commit reverted and see if the problem is gone.
