(perl) Pinging a bad file and dying causes seg fault.

[wilburlo]

Hi!

I've tested this in Image::Magick 6.3.3. This program produces a segmentation fault when run.

TIA,

-daniel

Code: Select all

#!/usr/bin/perl

use Image::Magick;

my $image=Image::Magick->new();

open my $fh, '>', 'bad.jpg';
print $fh "WEEEEE";
close $fh;

# pings of very non-valid jpgs causes seg faults.
my @stuff = $image->ping('bad.jpg');

die "this causes a seg fault\n";

Your program runs fine with the latest ImageMagick release 6.3.5-6.

[wilburlo]

I've asked our sys. admin. to install the latest image magick, and I will try again.

Thank you for your time,

-daniel

Our sys. admin. just upgraded image magick on one of our servers, I ran the program again and it segment faulted.
We are using Image-Magick 6.3.5-6
perl 5.8.8
FreeBSD 6.1 stable.

Here is a sample run,

Is there any information or anything else I can do to help you solve this problem?

Regards,

We can't reproduce the problem under Fedora or Centros. Can you post a stack trace so we know the fault is within PerlMagick or ImageMagick.

[wilburlo]

I wasn't able to get a stack trace for you; our sys. admin is currently away, and I'm not sure why the command isn't working. I will get back to you tomorrow.
