perlmagick segfaults when drawing text on individual images

[naoliv]

Hi!

From this bug report on Debian http://bugs.debian.org/351604:

The following script makes perl segfault:

Code: Select all

  use Image::Magick;
  my $img = Image::Magick->new;
  $img->Read('foo.jpeg');   # foo.jpeg exists
  $img = $img->[0];
  $img->QueryMultilineFontMetrics(text=>"foo bar");

I can reproduce it with Perl 5.8.8 and ImageMagick 6.3.7-9

gdb output is:

Code: Select all

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0xa7dc68c0 (LWP 20551)]

#2  0x080bf2fb in Perl_runops_standard ()

#4  0x08063752 in main ()

Is it a real problem with ImageMagick?

Thank you!

We have a patch in ImageMagick 6.3.9-10 Beta to fix the problem you reported. 6.3.9-10 will be available sometime tomorrow.
