Verified that your change worked for my compiler. Thank you!

GCC 8 release notes indicate that C++17 support is still be a bit experimental for the standard library. Anyway, can you try https://github.com/OSGeo/gdal/pull/12231<https://urldefense.com/v3/__https:/github.com/OSGeo/gdal/pull/12231__;!!ACWV5N9M2RV99hQ!LLypbO_HDg16BnOo4IDARi1zrLUzkmyWhmjNTbwBoT0ieGdQEl9YHkmMpYB1ld6UKWExDemX6KdmuKiu28xp8Ye6fs7T$> ? I don't have access to your compiler so I couldn't check with it, but I'd assume it should make template deduction easier for the compiler.
