Crash on Gentoo and Ryzen 9

[KingDuckZ]

Is there an existing issue for this?

• This is a bug in RetroArch frontend
• I have searched the existing issues

Description

Retroarch segfaults immediately after launching. From a git bisect I identified ecfa532 as the first bad commit.

Expected behavior

Retroarch should start normally

Steps to reproduce the bug

1. git reset --hard ecfa53255b5a69d1860cdc1a43e50c414a6073f7
2. git clean -fdx && ./configure --enable-systemd --enable-dbus --enable-freetype --enable-pulse --enable-sse --enable-vulkan --enable-threads --enable-spirv_cross --enable-qt --enable-flac --enable-v4l2 --enable-al --enable-zlib --enable-alsa --enable-x11 --enable-sdl2 && make -j16
3. ./retroarch

Playing around with a --enable-debug build, log ends with:

[ERROR] [Vulkan] Failed to get context data.
[ERROR] [Video] Cannot open video driver. Exiting...
[ERROR] Fatal error received in: "video_driver_init_internal()"
[INFO] [Core] Unloading core...
[INFO] [Core] Unloading core symbols...

gdb doesn't offer much more insight as it's not crashing. On a regular, crashing build I get this backtrace:
