Hello
I've a strange problem with apache2.0, gd2 and mod_perl2.
I wrote a small test script which creates a png file in my /tmp
directory.
This perl script works fine if I run it localy on a shell, it works also
as normal cgi script but it doesn't work with apache2 and mod_perl2. It
crashes with: print HF $im->png; (see the whole script below)
httpd-error.log message (debug enabled)
[Tue Feb 13 09:41:34 2007] [notice] child pid 24480 exit signal Abort
trap (6)
t/www in free(): error: pointer to wrong page
The script I'm talking about:
cat buttontest.html
#!/usr/bin/perl
use GD;
# create a new image
$im = new GD::Image(100, 100);
# allocate some colors
$white = $im->colorAllocate(255,255,255);
$black = $im->colorAllocate(0,0,0);
$red = $im->colorAllocate(255,0,0);
$blue = $im->colorAllocate(0,0,255);
# make the background transparent and interlaced
$im->transparent($white);
$im->interlaced('true');
# Put a black frame around the picture
$im->rectangle(0,0,99,99,$black);
# Draw a blue oval
$im->arc(50,50,95,75,0,360,$blue);
# And fill it with red
$im->fill(50,50,$red);
print "Content-type: text/html\n\n";
print "<h1>Hello world</h1>";
# make sure we are writing to a binary stream
open HF, ">/tmp/file.png";
binmode HF;
# Convert the image to PNG and print it on standard output
# here it crashes with apache
print HF $im->png;
close HF;
print "<p>Foobar";
my httpd.conf:
LoadModule perl_module libexec/apache2/mod_perl.so
PerlModule Apache2::Reload
<Location /perl>
# -- mod_perl stuff
SetHandler perl-script
PerlResponseHandler ModPerl::RegistryPrefork
PerlInitHandler Apache2::Reload
Options +ExecCGI
AddHandler cgi-script html png
PerlOptions +ParseHeaders
PerlSetVar StatINCDebug On
</Location>
My System:
6.2-RELEASE-p1 (i386)
Packets I use:
apache-2.0.59
png-1.2.12_1
perl-5.8.8
p5-GD-2.35
mod_perl2-2.0.3_
gd-2.0.33_4,11,3
freetype2-2.2.1_1
I compiled everything with -DWITHOUT_X11 knob but I also tested it with
X support too. It doesn't work either. I also tried mod_perl2-2.0.2 to
make sure it's not a new 2.0.3 bug.
The same script works fine on an Ubuntu Linux Server with apache2.0.x,
mod_perl2 and gd.
Any idea?
Regards,
Thomas
