Duration: 44.0s elapsed (35.3s cpu).

I'm not sure the cause, but filing first. It could well just be an r-devel bug that will resolve itself.

I don't reproduce the issue locally on r87668 on Linux. The failing run is r87664. The last passing test we have in Windows GHA is r87642.

I also don't reproduce on r87664 locally. But we do see the error on Linux on CRAN (hence removed the platform-specific label).

Locally I have:

gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0

The failing CRAN server is using:

GCC 14.2.0 (Debian 14-2.0-12)

GHA has

* R was compiled by
    gcc.exe (GCC) 13.3.0
    GNU Fortran (GCC) 13.3.0

Maybe my gcc is too old...
