Which indicates that it is indeed a bug, and probably one not that
difficult to fix, by having fread call some alias of read instead. Of
course, it gets more complicated when the same has to be done for all
The second example is not as clearly a bug. I would argue that you're
simply not allowed to have a local symbol called mlock if you want to
use the pthread library. I don't know what POSIX says on the issue
