           Summary: Cairo segfaults when perl-Cairo testsuite is run
           Product: openSUSE 10.3
           Version: Alpha 2plus
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: GNOME
        AssignedTo: bnc-team-gnome@forge.provo.novell.com
        ReportedBy: anicka@novell.com
         QAContact: qa@suse.de

Since last version update of cairo, my package perl-Cairo fails to build in
autobuild due to the test fail - cairo segfaults during the test run.

This is the minimal piece of the original test, which causes segfault:

#!/usr/bin/perl -w
use strict;
use warnings;

use constant {
        IMG_WIDTH => 256,
        IMG_HEIGHT => 256,
};

use Cairo;

my $surf = Cairo::PdfSurface->create_for_stream (sub { die 'write-error'; },
'blub', IMG_WIDTH, IMG_HEIGHT);

And this is a backtrace:

Program terminated with signal 11, Segmentation fault.
