Bug Report

What's the issue you encountered?

While attempting to build/port the Dolphin emulator to the Switch, an internal compiler error was encountered (consistently) from a const std::string& initialization. See below, along with the dump at the bottom:

Source/Core/Common/IniFile.cpp:39:43: internal compiler error: in build_cleanup, at cp/decl2.cc:3750

How can the issue be reproduced?

I had no part in the creation of dolphin.

Configuring with the devkitpro switch toolchain, then building the dolphin-nogui make target consistently gives this ICE on this commit: https://github.com/auggeythecat/dolphin-nx/tree/7f6e49d96f30e51b2d0852ddf5cdc42574e65287

Environment?

Windows 11, running an arch linux WSL distro (archlinux).

Apologies if I didn't redact anything properly

Thank you so much more making the tools/toolchain, let alone dedicating time to stuff like this!
