When I worked at qcom it took 2 devs 3 managers and 2 directors to get another group to let us fix a single race condition in their code. Once I got a copy of the code I started handing off tons of memory overwrites and underruns back for them to fix and another 10 or so race conditions. Their initial stance was 'there is nothing wrong with the code it is your code that is broken'. That was internal in the same vertical. It would be awful to work as an external group with that lib. Other stacks I got to look into were in similar shape. Some groups if you got their code you knew it was going to be solid and you would learn a thing or two. Others groups you were kind of surprised it compiled.
