These lines of code produces a segfault in PHP, test with 4.2.3 and 4.3.2RC3 cli.

The problem might be that it goes into an infinite function loop as I get 3629 frames in by backtrace.



<?php
        include 'Spreadsheet/Excel/Writer.php';
 
        $wb = new Spreadsheet_Excel_Writer('test.xls');
         
        $ws =& $wb->addWorksheet('1');
        $ws->writeFormula(0, 0, "=SUM('Music Denmark'!C2:C31)");
 
        $wb->close();
?>
