Description:
------------
When running imagettfbbox() against a font, the returned values are way off, in the billions or negative billions.

Reproduce code:
---------------
print_r(imagettfbbox(9, 0, "HelvCondBlack.TTF", 'HOME'));

HelvCondBlack.TTF is available for download at http://www.campai.nl/fonttest/HelvCondBlack.TTF

Expected result:
----------------
Array
(
    [0] => -1
    [1] => -1
    [2] => 21
    [3] => -1
    [4] => 21
    [5] => -8
    [6] => -1
    [7] => -8
)



Actual result:
--------------
Array
(
    [0] => 1080490528
    [1] => 153840736
    [2] => -1073754904
    [3] => 1081352559
    [4] => 1080490544
    [5] => 1080487896
    [6] => -1073754872
    [7] => 1079718188
)
(The 2nd item, [1], will fluctuate mildly between requests)

Works fine with 4.3.9 i got here using bundled libgd, are you using bundled lib gd or the external one? What GD related configuration flags do you have enabled?

From phpinfo()'s configure string:
--- 
'./configure' *snap* '--with-gd' '--enable-gd-native-ttf' '--with-t1lib' '--with-jpeg-dir=/usr/lib' '--with-png-dir=/usr/lib' '--with-ttf' *snap*
--- 

From the GD table in phpinfo():
--
                GD

GD Support          enabled  
GD Version          bundled (2.0.28 compatible)  
FreeType Support    enabled  
FreeType Linkage    with TTF library  
T1Lib Support       enabled  
GIF Read Support    enabled  
GIF Create Support  enabled  
JPG Support         enabled  
PNG Support         enabled  
WBMP Support        enabled  
XBM Support         enabled

Comparing it to a similar server, still running 4.3.0, which DOES give the right results, I noticed a small difference in the compile strings:

OK: '--with-ttf' 

WRONG: '--enable-gd-native-ttf' '--with-t1lib' '--with-ttf'
 [2004-10-04 14:28 UTC] cipri@php.net 
After having PHP recompiled with the following items in the ./configure string everything started working again:

'--disable-gd-native-ttf'

It would thus seem to be a problem with GD's native TTF Functions...

Seems to be fixed using the right ft.
