New Comment:
According to Sean, this appears to be a bug in libgd that has been fixed
in the
copy included by PHP but not at upstream. I'm afraid I don't know any
other
detail.
Pierre, could you please take a look at it? (and if possible, update
libgd
upstream :)

I tried with the following versions and with all of them the result is
the same:
4.1.2, 4.2.4, 4.3.4, 4.4.3
So it's a bug on libgd's side. Will ask Sean as he is the maintainer at
Debian.

Strange that you mention that it works with gcc 4.1.2. Last I heard
5.3.x failed to build with that version (don't know what arch was that,
though).
Will take a look at it later. FWIW, a test related to imagettfbbox is
reproducibly failing (with the same results on all archs):
ext/gd/tests/bug48801.log:
---- EXPECTED OUTPUT
(-1, 15)
(155, 15)
(155, -48)
(-1, -48)
---- ACTUAL OUTPUT
(1, 15)
(163, 15)
(163, -48)
(1, -48)
---- FAILED
And that was with 4.4.3 (same results without optimisation). Has anyone
tried to reproduce it with the same or similar versions of gcc from
another distribution?

So I have find the origin of the problem : "GCC".
This problem appear if you compile PHP 5.3.2 width GCC 4.3.2 on Debian
32 bits. For fix the problem you must compile PHP 5.3.2 width GCC 4.1.2.
