I can see that the README states that the lowest tested gfortran is v13, and that the library is possibly not expected to build with lower version. Reporting here nevertheless to document the issue.

The issue occurs with --profile debug as well.

Correction, v12.3 doesn't encounter this issue.

@nedtaylor Can you put an update to the README.md that the library works with v12.3?

Leaving this issue open for now as I will look into why it fails for v11.4 and whether this can be fixed at some point.
