/usr/bin/convert: free(): invalid pointer

Posted: 2012-12-19T10:16:50-07:00
by aaronh
Im getting this on my website when a user clicks on an image in our catalog. I have imagick module 2.3.0 and ImageMagick-6.4.3.6-5.3 and ImageMagick-devel-6.4.3.6-5.3 installed on my server.
Also, I'm using Drupal 6 as my CMS.

From what I'm seeing, there must be an invalid use of free() in convert.

The full error is:

Code: Select all

ImageMagick reported an error: *** glibc detected *** /usr/bin/convert: free(): invalid pointer: 0x0000000000a2dbb3 ***
This is the backtrace:

Its possible you have a corrupt profile in one of your images. Post a URL to one or two of your images that fail to convert. We need to download it and reproduce the problem before we can comment further.

This url is from one of the catalog pages:
http://www.timelessexpressions.com/post ... uthor-997|

you may have to refresh the pages to get the error to pop up

We downloaded a3304738709dc921365828ae4ce66065.jpg from http://www.timelessexpressions.com/post ... 1118045709 and it does not contain a profile so its likely not the image causing the exception. Once you identify the exact image that causes the invalid pointer exception, let us know. We'll report if the image is corrupt and if recent versions of ImageMagick can read it despite the corruption.

There are tons of images on our site. How will I know the one corrupt image when I see it? Should I just upgrade?

You understand the conundrum, we can't help you unless we can reproduce the problem and we don't know how your site works so we can't help you identify the problematic image. Upgrading ImageMagick may help, your version of IM is quite old and a newer version may have bug fixes.
