In FreeBSD 8.0
After update all port:
#portmanager -u

This problem resolved...

Unfortunately, upgrading and reinstalling all of PHP related ports does not solve 
the problem.

Not a php problem then :)

Please provide the PNG image you use as test.

Image does not matter. Any PNG image I have tested lead to the same result -- 
core dumped. Already tested that on two machines.

You may test on that image, for example:

Then it is definitively not a PHP problem. The tests suite work just fine, and all PNGs I use for testing as well (from the PNG tests suite and some other). Please report the issue to FreeBSD or update it as suggested in the other comment.

I can reproduce this on  FreeBSD 8.2-RELEASE (amd64)

the test script is
<?php
$im = imagecreatefrompng("test.png");
echo 'ok';
?>

test.png can be found at https://gg.net.nz/X/test.png


If I have the pdf extension loaded before gd (in extensions.ini) then I get an abort
--- snip of extensions.ini ---
extension=pdf.so
extension=gd.so
---
% php test.php
zsh: abort (core dumped)  php t.php


If I load gd first then the issue goes away
--- snip of extensions.ini ---
extension=gd.so
extension=pdf.so
---
% php test.php
ok          


The software versions are:
php5-5.3.8
php5-gd-5.3.8
pdflib-7.0.4
pecl-pdflib-2.1.8
png-1.4.8

By changing the order in extensions.ini the problem doesn't go away.
It's moved to the latter module.

with sequence;
--- snip of extensions.ini ---
extension=pdf.so
extension=gd.so
---
pdf_load_image($pdfObject,"png", 'someimage.png'); will work
But png functions from GD won't!

with sequence;
--- snip of extensions.ini ---
extension=gd.so
extension=pdf.so
---
GD works but pdf_load_image will segfault.

doing portupgrade will alter the sequence in extensions.ini so GD works and it looks like problems are solved. But loading png in pdf will fail.

Enviroment;
Freebsd 8.2-RELEASE php5.3.10
just did portmaster -r png (13-feb-2012)

Confirmed and duplicated on FreeBSD 7.3-RELEASE. Moving a crashing extension to the top just moves the bug down. I am unable to find any determinism (which doesn't mean none exists) in this. 

I appreciate that both the FreeBSD camps and PHP camps are pointing at each other. It would be greatly appreciated by those of us having a problem if someone from both camps could take a cooperative look. Thank you. :)

I found that recompiling all pecl extensions solve the problem, so this is some 
kind of dependency problem.
 [2012-05-22 08:38 UTC] andy at fud dot org dot nz 
Putting the following patch in /usr/ports/print/pdflib/files/patch-pngusr.h and 
recompiling pdflib fixes the issue. There was a namespace conflict between the 
static png lib inside libpdf and libpdf.so.

https://gg.net.nz/X/patch-pngusr.h

I will get this committed to the pdflib port.
 [2012-06-06 01:54 UTC] andy at fud dot org dot nz 
Updating to print/pdflib to 7.0.5_1 will resolve this issue.
