glib is basically the C++ STL written in C, but lacking exceptions so
that there's no way to handle errors.

While debugging the heap-check crash that turned out to be memalign, I
dug into the glib and libxml2 code a bit. Just casually inspecting
less than 500 lines, I found cases of UB that don't break now but will
break down the road with fancier compilers, lack of synchronization
where needed, and various other small to medium bugs, not to mention
75%-redundant code in multiple code paths (lack of any proper
factoring). Offhand I would guess the whole GNOME family of code has
something like 4-10 bugs per 100 LoC....
