For the life of me, I cannot figure out why I cannot reproduce this error outside of my main project. This is with Perl 5.20 and I am trying to get the security information for a registry key. Here is the code as written in my main project followed by a code snippet that I have tried running outside of the project to reproduce the error.

sub getEffectiveRights
{
    my $object = $_[1];
    my $objectType = $_[2];
    my $binarySid = $_[3];
    my $error = undef;
    my $result = undef;

    # Establish variables.
    my $psidOwner;
    my $psidGroup;
    my $pDacl;
    my $pSacl;
    my $pSecurityDescriptor;

    try
    {
        $logger->debug("Object: $object");
        # Call GetNamedSecurityInfo. This is to get the DACL.
        ($psidOwner, $psidGroup, $pDacl, $pSacl, $pSecurityDescriptor)
+ = Win32::Security::Raw::GetNamedSecurityInfo(
            $object, $objectType, 'DACL_SECURITY_INFORMATION');
        print "returned from Win32::Security::Raw::GetNamedSecurityInf
+o\n";
        unless (defined($pDacl))
        {
            throw Error::Simple("An error occurred trying to access th
+e discretionary access control entries for security object '" . $obje
+ct . "'.");
        }
        
        # Build the trustee structure.
        my $trustee = System_Functions->buildTrusteeWithSid($binarySid
+);
        
        # Get the access mask.
        $result = System_Functions->getEffectiveRightsFromAcl($pDacl, 
+$trustee);
    }
    catch Error::Simple with {
        $error = shift;
        print "error = $error\n";
    }
    finally
    {
        # Clear memory.
        if (defined($pSecurityDescriptor))
        {
            Win32::Security::Raw::LocalFree($pSecurityDescriptor);
        }
    };

    if (defined($error))
    {
        throw Error::Simple("Could not access '$object'. Verify that i
+t exists and that you have permission to access it. $error");
    }
    return $result;
}

And the script that works outside of the main project:

use warnings;
use strict;
use Win32::Security::Raw;

#my $object = "MACHINE\\SYSTEM\\CurrentControlSet\\Services";
my @objects = ("MACHINE\\SYSTEM\\CurrentControlSet\\services","MACHINE
+\\SYSTEM\\CurrentControlSet\\Services","MACHINE\\SYSTEM\\CurrentContr
+olSet\\services\\.NET CLR Data", "MACHINE\\SYSTEM\\CurrentControlSet\
+\services\\Lsa\\Performance");
my $ObjectType = 'SE_REGISTRY_KEY';
my $SecurityInfo = 'DACL_SECURITY_INFORMATION';

# Establish variables.
my $psidOwner;
my $psidGroup;
my $pDacl;
my $pSacl;
my $pSecurityDescriptor;

foreach my $object (@objects) {
    print "object = $object\n";
    # Call GetNamedSecurityInfo. This is to get the DACL.
    ($psidOwner, $psidGroup, $pDacl, $pSacl, $pSecurityDescriptor) = W
+in32::Security::Raw::GetNamedSecurityInfo($object, $ObjectType, 'DACL
+_SECURITY_INFORMATION');
    print "$psidOwner, $psidGroup, $pDacl, $pSacl, $pSecurityDescripto
+r.\n";

    if (defined($pSecurityDescriptor))
    {
        Win32::Security::Raw::LocalFree($pSecurityDescriptor);
    }
    print "\n\n";
}

I noticed that Win32::API, which is called by Win32::Security::Raw, changed significantly since Perl 5.12 and now has buffer overflow protection built-in but I'm unsure why it would be complaining about "parameter 1". Any help would be greatly appreciative as this is preventing us from upgrading to Perl 5.20.
