It returns NULL, leaving the original memory it wanted to resize
untouched (which is why you should never do something like "ptr =
realloc(ptr, size);" since you have a memory leak if realloc() returns
NULL.)
I did my own patch for the readlink() problem and fixed a few other
things...the latest in the default branch (and stable-2.0 branch) should
fix the issues. Let me know if it doesn't.
