There have been numerous crash-bugs for the Windows font renderer, and even security exploits using it (especially before windows 10, as earlier than that font rendering was performed in the kernel's space rather than user-land). I wouldn't be surprised to learn of issues (at least of the falling over variety) in common Linux rendering engines and for other OSs too.
The Windows bugs are usually tied into executing TTF hint bytecode which is ignored by Freetype.
FreeType used to ignore TrueType hint bytecode to avoid infringing on related patents, but those patents expired in 2010 and FreeType's interpreter is now enabled by default.
