 	/* rgerhards 2005-10-19: The free of pBuf was contained in conditional compilation.
 	 * The code was only compiled if STRINGBUF_TRIM_ALLOCSIZE was set to 1. I honestly
 	 * do not know why it was so, I think it was an artifact. Anyhow, I have changed this
 	 * now. Should there any issue occur, this comment hopefully will shed some light 
 	 * on what happened. I re-verified, and this function has never before been called
 	 * by anyone. So changing it can have no impact for obvious reasons...

+	 * rgerhards, 2008-02-20: I changed the interface to the new calling conventions, where
+	 * the destructor receives a pointer to the object, so that it can set it to NULL.
