Thanks for the report @jcorporation. However, I'm using the correct size here, so I think this is a false positive and not a bug in inih. What version of gcc is this? This SO answer seems to indicate it's a false positive / bug in GCC 9.

gcc version 9.2.1 20191008 (Ubuntu 9.2.1-9ubuntu2)

Thanks for your fast response.
