Legacy ImageMagick Discussions Archive

Source file: https://www.dropbox.com/s/a218rgxd4srwe9y/d54227aa?dl=0
To reproduce: Output: System Details:
AMD64
Distributor ID: Ubuntu
Description: Ubuntu 14.04.1 LTS
Release: 14.04
Codename: trusty

ImageMagick 6.9.0-1 Beta compiled from source.
Also crashed on IM 6.9.0-0 from Ubuntu.

Found with American Fuzzy Lop ( http://lcamtuf.coredump.cx/afl/ )
I have a 24-core box going 24/7 on this so I'm sure there will be more tomorrow.

We cannot reproduce the problem. We're getting expected results:

I also need a patch for this

Tested 12/15/2014 with http://www.imagemagick.org/download/bet ... 215.tar.gz Result: Fail

Can you try with a newer beta or a svn checkout? I am getting the following output:

Tested 12/17/2014 with http://www.imagemagick.org/download/bet ... 217.tar.gz Result:Fail

I just tested this on my Ubuntu machine and it exits properly there:
Are you sure you are using the correct version of ImageMagick?

Looks like you're running lt-convert while I am running convert.

Works now that I fixed the libs.
