Will confirm as I can get some fonts to crash, but not all. In my case I attempted to load a random system font called 8514oem.fon which yielded the same stack as above. The font->ft_size field is null and traced the following just before crashing:

Code marked as unreachable has been executed. Please report this as a bug.
Error found at C:\Users\blender\git\blender-vdev\blender.git\source\blender\blenfont\intern\blf_font.c:1617 in blf_ensure_size.

The font "works" in 3.3 but is not readable and is just some squiggles. That version prints the following:
The current font does not support the size, 22.000000 and DPI, 72
