No.  Copyright protects the form of expression, not the content.  If
there was a patch in the bug report and they apply the patch, it is a
derivative.  If the bug report explains the correct algorithm by
providing an equation, it is not a derivative to implement that
equation in C.

This is pretty basic stuff; there are discussions on it at the GNU
website ( is one place to start), and at
the Open Source Initiative site ( IIRC), and
probably at, among others.
