I checked the bug reports and did not see this as an issue, so hopefully no one will get too mad at me for posting this...I'm a virgin to bug reporting :).

When using the Spreadsheet_Excel_Writer package for PEAR, formulas must be written in capital letters.  In other words, you can not write "=SUM(a1:a10)".  It must be written as "=SUM(A1:A10)".

A simple fix for this is the following:

Edit the writeFormula() function to include

$formula = strtoupper($formula);

as the first line of the function.

I don't know if this is the best way to fix the problem, but this is my first bug report/patch, so it looks good to me :).

Reproduce code:
require_once 'Spreadsheet/Excel/Writer.php';

// We give the path to our file here
$workbook = new Spreadsheet_Excel_Writer('C:\\bugs\\bug.xls');

$worksheet =& $workbook->addWorksheet('My first worksheet');

$worksheet->write(0, 0, 1);
$worksheet->write(1, 0, 2);
$worksheet->write(2, 0, 3);

// Formula must be in upper case.  This line will not work.
$worksheet->write(3, 0, "=SUM(a1:a3)");

// We still need to explicitly close the workbook

Expected result:
Apache.exe - Application Error

The exception unknown software exception (0xc00000fd) occurred in the application at location 0x0084823d.

I don't think we really want to accept "formulas" in lowercase. 

But the big point of this is why is it segfaulting? We need a better handling of this m'be?

Just a short note:
Maybe strtoupper is a bit "too easy" tought. Aren't there also strings allowed in Formulars? Like when you say "if >0 say 'Bigger', if <0 say 'Lower'". Fixing this with strtoupper would brake those strings.
