Does this happen on the latest release?

Hello,

I have the same issue from the tag v5.3.1 and v5.4.0 using g++ 13.2.0 on debian.
When i build with the parameter -DCMAKE_BUILD_TYPE=Debug it compile but when i build with
-DCMAKE_BUILD_TYPE=Release I have the same error and it doesn't compile.

[Daniel Simon]

Seems to still be the case with v5.4.1 and both GCC 13.2.0 and GCC 14.0.1. Release and MinSizeRel fail, while Debug and RelWithDebInfo compile fine.
Same version compiles fine under Clang 18.1.3

Just check the problem. The issue is fixed any more.
