Description:
------------
If I have a function that has a do..while(); construction in it, inside a block container { }, PHP will segfault on exiting the block container UNLESS I have a statement in between the end of the while (); and the closing brace of the block.

This does NOT happen in "global" execution.  A do..while() loop that lives outside any function's scope works just fine; I have several other do..while() constructs outside of functions that work with no problems.  The segfault seems to only happen when the do..while(); is inside a function AND inside a block container (in this case, belonging to an if statement).

Any ideas?

Reproduce code:
---------------
function announce()
{
	global $totalRows_announce, $row_announce, $announce, $srs;

	$ann = "";

	if ($totalRows_announce > 0) {
		do {
			$author = mysql_result(mysql_query("SELECT nick FROM players WHERE id='".$row_announce['author']."'", $srs), 0, "nick") or die(mysql_error());
			$msg_body = stripslashes(implode("<br>",explode("\n",$row_announce['msg_body'])));
			$ann .= textBlock(textBlock($row_announce['subject'], "", "anntitle") . br() . 
				textBlock("Posted by:".$author." | On: ".$row_announce['posted_date'], "", "annhead") . br() .
				textBlock($msg_body, "", "annbody"), "", (($row_announce['urgent'] == 1) ? "redrow" : ((($ctr++) % 2) ? "lightrow" : "darkrow"))) . br();
		} while ($row_announce = mysql_fetch_assoc($announce));
        // Segfault happens HERE
	} else {
		$ann = textBlock("No Announcements", "", "loginerr");
	} 
	return $ann;
}


Expected result:
----------------
The code, as intended, returns a string of HTML code to the calling function.

Actual result:
--------------
The code immediately segfaults when it encounters the closing brace of the do..while() loop's block container UNLESS there is an intervening statement.
