That pretty much looks like a bug in either the compiler or the standard library. Try updating your toolchain to a more recent version.

If you want to cross-compile FileZilla Server for Windows, we recommend always using the MinGW toolchain that's part of Debian stable.

[catmark]

The problem looks fixed with latest LLVM 17.0.6.
