Description:
------------
Hi,

I have ugraded PHP 5.2 to PHP 5.3.2 on my Debian server and I have found
a bug width ths function imagettfbbox.

Sometimes the text don't show on the image generated :

http://www.exinsidephp.com/cache/example.png

If I refresh the page (Ctrl+F5) another image don't display the text :

http://www.exinsidephp.com/cache/example2.png

Any error on PHP Blog, any error on syslog or kernel log... I haven't
find any trace of error. Someone have the same issue ?

The PHP Package come from http://www.dotdeb.org/ website. The
list of
modules installed (dpkg -l | grep php5) :
