Indeed, and it seems that my reversing this patch is what caused the issue (IOW, I can't crash Emacs any more after re-applying the patch). Interestingly, if I use 'light as the weight, the right font is selected, and everything works fine (that is, the default frame font changes and Emacs doesn't crash). But for some reason, x-select-font returns a font-spec in semi-light, and then set-frame-font crashes. > Why do you still have that commit reverted, btw?
