shittiest famous library

What is the shittiest famous library, in your opinion, and why?

My vote goes for iText.

Maybe it's not that shitty, but the developers are huge faggots, I hope all those people die in a fire.

>● Shitty strings

and shitty string functions.Namely strncpy. Why the fuck

      If the length of src is less than n, strncpy() pads the remainder of dest with null bytes.

Who the fuck thought that it is a good idea? It makes no sense.

In C it's impossible to copy string no longer than N fast. memcpy can not stop at 0 byte. strcpy is not safe. strncpy happily fill most of buffer with zero, though it most probably already was a zero. And strncat does the same shit.
