hi,
im running apache-2.2.0_7 on 6.1-RELEASE within a jailed environment. PHP4 has
been compiled without Suhosin patch and its pretty much all in default
configuration, so no restrictions.
Now, the Problem: running gallery, which calls various ImageMagick binaries in
order to resize Images, fails with the following Error message in
httpd-error.log:
[..]
convert in free(): warning: junk pointer, too high to make sense
convert in free(): warning: junk pointer, too high to make sense
convert in free(): warning: junk pointer, too high to make sense
convert: Memory allocation failed `Permission denied'.
[..]
a hackish PHP script in order to reproduce this failure (note, the image size
has to be bigger than 150x150):
<?
system("convert -size 150x150 -quality 50 -thumbnail 150x150 1.jpg 2.jpg");
?>
now, this script does *not* fail if im calling it from php's cli interface
(with the same php.ini used). I can also easily convert the image calling
convert from some random shell. The interesting part is, i dont have to convert
something in order to reproduce this error, i can simply replace the above
convert call with
<?
system("convert -list resource"); [0]
?>
in order to make it bail out. Any Ideas? I've been using apache2.0.x before and
never had any problems running Gallery at all (before upgrading to 6.1-RELEASE
and apache2.2).
