Comment:
You are expected to allocate a dirent structure big enough for the names
of the files in the directory. The d_name array in the struct definition
only has space for one character. In this case, readdir_r scribbles over
plugindir, causing the second call to readdir_r to fail and the call to
closedir to crash.
The reason it works on Linux is because struct dirent has a larger d_name.
But since POSIX doesn't specify the length of the array, portable code
shouldn't rely on that.
