PHP running as an Apache v1.3.9 module.

The following script:

<?php
$current_time = date("M j Y g:i A");
?>

causes a segmentation fault of the process running the script if it is run when the hour of the local time is 2 digits (ie between 10am and 12pm and 10pm and 12am). 

The problem can be traced back to the _php3_date() function in functions/datetime.c. The switch case for computing the size of the string required to hold the formatted date does not increment the size by 2 for the 'g' and 'G' cases. It is incorrectly incremented by 1.
