Building main with Clang results in a segfault on launch

### Mods and Forks

- [x] The bug occurs on an **official release** of Dusklight, without any forks or third-party patches installed

### Dusklight Version

HEAD (5f0f3d4 ATTOW)

### Bug Description

Using either the `linux-clang-debug` or `linux-clang-relwithdebinfo` build profiles to build Dusklight results in a `SEGV_MAPERR` when launching Dusklight. Seems to be related to **cxxopts** but I'm not entirely sure.

Building with `linux-default-debug` or `linux-default-relwithdebinfo` works completely fine.

### Steps to Reproduce

1. Configure cmake with `linux-clang-debug` or `linux-clang-relwithdebinfo`
2. Build Dusklight with the same profile
3. Launch the Dusklight executable
4. See segfault

### Expected Behavior

Dusklight doesn't segfault when launching after being built with Clang.

### Current Behavior

Dusklight segfaults when launching after being built with Clang.

### OS / Architecture

Linux x84-64

### Game Disc

GameCube PAL (Europe)

### Game Language

English

### Graphics Backend

Vulkan

### Texture Packs and Mods

N/A - Dusklight doesn't even access the config folder before crashing. Can rename / remove `~/.local/share/TwiliRealm/Dusklight` and a new one isn't created.
