Comment 3 Jan Henke 2022-12-28 12:30:53 UTC 
I notice in the build log that is error occurred with GCC 12, which explains why I did not see it locally when building.

Note: This package is header only, the source files are part of the test suite, thus it can still be used normally.

I will raise this issue with upstream and see if they come up with a fix.
