I've hit this twice now in local builds; I suspect 'vendor' is a nullptr, but gdb says it's "optimized out" (likely in a register). We crash calling strcmp(vendor, "ARM").
I'll attach a gdb log poking around

FYI, I've been hitting this a LOT at startup (not 100%, but a lot) in debug builds. I'm running Fedora 34. I have a stack of other patches I'm testing, but nothing should have touched gfx/gl, though they may have shifted some timing

Do you have the proprietary Nvidia driver installed, but are not using it? (libglvnd has a bug: bug 1737078)
Do you have multiple graphics cards?
Are you using Wayland, Xwayland or X11?

I'm continuing to hit this in local debug builds, maybe one in 4 runs

https://hg.mozilla.org/mozilla-central/rev/64da1a6eb723 should have fixed this a week ago. Where is it crashing now?
