Description:
------------
Calling imageftbbox() multiple times with the same arguments gives
substantially differing results if the text contains a newline.
The exact results vary between executions, so an uninitialized variable
or buffer overflow is suspected.
The results are similar whether the function is run in Apache or from
the command line.
Changing fonts or the text doesn't have an effect, so long as the text
contains a newline (\n).
Occurs using the standard Fedora Core 1 php-4.3.4-1.1 from RPM, and
also php4-STABLE-200402271630 (configure --with-gd).
P.S. the provided email address is valid as-is.
Reproduce code:
---------------
#!/usr/bin/php -q
<?php
$size=8;
$angle=0;
$font="/usr/share/fonts/bitstream-vera/Vera.ttf";
$text="foo\nfoo";
$extra=array();
for ($i=0;$i<10;$i++) {
$box=imageftbbox($size,$angle,$font,$text,$extra);
echo $box[1]." ".$box[3]."\n";
}
?>
Expected result:
----------------
1 1
1 1
1 1
1 1
1 1
1 1
1 1
1 1
1 1
1 1
(Perhaps not this exactly, but all the lines should be the same)
Actual result:
--------------
1 1
15 15
15 15
15 15
15 15
15 15
15 15
15 15
15 15
15 15
(On occasion, the second line may match the first, but from the third
line on things change)
