When running HIP CI with GCC version 14 or 13 we bump into an issue that is essentially identical to llvm/llvm-project#69288. The issue seems to happen whenever <format> is included (directly or indirectly) in device code, even if no functionality is actually used on the device. This means that HIP currently has to be used with GCC <= 12.

One possible workaround would be to try to avoid including <format> in device code, since it's unlikely to be used there, but this may be close to impossible to do exhaustively.
