 * than it strictly need to. So, it's not possible to append stuff to the symbol
 * or anything of that kind.
 * @returns Pointer to the duplicate.
 *          This must be freed using kDbgSymbolFree().

 * Frees a line number obtained from the kDbg API.
 * @returns 0 on success.
 * @returns KERR_INVALID_POINTER if pLine isn't a valid pointer.
 * @param   pLine       The line number to be freed. The null pointer is ignored.
