AUTOLOAD is going into an infinite loop trying to reflect a constant, eating up the entire "C" stack. That's the memory you're running out of.

I'm curious as to what is being autloaded. I'd add a print statement to Image/Magick.pm to print out $constname.

The immediate cause of the problem is probably $! =~ /Invalid/ returning false when it is intended to return true. I'd add a print statement to Image/Magick.pm to print out (0+$!).":$!".

Of course, that's assuming your version of Image::Magick is anything like the latest one. You haven't provided any version info.

By the way,
eval { require Image::Magick };
my $is_Magick = $@ ? 0 : 1;
is simpler and safer when written as
my $is_Magick = eval { require Image::Magick; 1 };

It seems like he didn't install imagemagick correctly (both perl bindings, and library)

That's would cause bootstrap to die, setting $is_Magick to false. All's good.

So what's calling AUTOLOAD?

PerlMagick runs out of memory says It stems from PerlMagick being unable to load libMagick.so: .... Once you figure this out -- by setting LD_LIBRARY_PATH to include the location of libMagick.so.10 or whatever else it takes on your OS -- the "runs out of memory" issue will go away too.

Hi ikegami and Anonymous Monk,

ImageMagick-6.4.4-2 and perl 5.10, PerlMagick is installed by the IM installer.

Everything worked fine with use Image::Magick.

ikegami , added a print $constname here

sub AUTOLOAD {
    # This AUTOLOAD is used to 'autoload' constants from the constant(
+)
    # XS function.  If a constant is not found then control is passed
    # to the AUTOLOAD in AutoLoader.

        my $constname;
   ($constname = $AUTOLOAD) =~ s/.*:://;

print "\nDEBUG " . $constname . "\n";

but nothing is printed. If I remove a concatenation point have an operator missing error. Did I put this in the wrong place ?

And, after a server reboot, the script worked 2 times and then went OOM again !?

thanks a lot and have a nice day !
