Illustration of compilation failure on Leap

While using a C++ compile time fixed_string library, I encountered an issue
with Leap's version of GCC 14.

I tried a number of combinations:
* GCC-13, C++20: Pass
* GCC-13, C++23: Pass
* GCC-14, C++20: Pass
* GCC-14, C++23: Fail

Testing on Tumbleweed all combinations passed.

Distro compiler versions reported by "g++-14 -v"
Leap 15.6: gcc version 14.2.0 (SUSE Linux)
Tumbleweed: gcc version 14.2.1 20241007 [revision
4af44f2cf7d281f3e4f3957efce10e8b2ccb2ad3] (SUSE Linux)

I've stripped down the code in question to produce a minimal reproducible
example (see attachment).

Since the code works with GCC 14.2.1 on Tumbleweed, is the Leap package lacking
upstream updates?
