Hi All,

I'm experiencing a strange problem. While the following piece of XML
passes through 'xmllint --valid' without problems it makes XML::LibXML
SIGSEGV during validation. On the other hand, almost all other XML
files with a DTD I have validate without problems. Is the problem
related to my configuration only or can also somebody else reproduce
it?

The XML:

<?xml version='1.0'?> 
<!DOCTYPE test [
 <!ELEMENT test (#PCDATA)> 
]> 
<test> 
</test> 

My configuration:

RH 7.2/7.3
perl 5.6.1
XML-LibXML 1.52/1.53/CVS
libxml-2.4.21/libxml-2.4.23

Here is a short test code:

#!/usr/bin/perl

use XML::LibXML;

my $parser=XML::LibXML-> new();
$parser-> validation(1);
my $doc=$parser-> parse_string(<<'EOF');
<?xml version='1.0'?> 
<!DOCTYPE test [
 <!ELEMENT test (#PCDATA)> 
]> 
<test> 
</test> 
EOF
print STDERR "parsed\n";                         # ok (even with validating parser)
print STDERR "validate: ",$doc-> validate(),"\n"; # SIGSEGV
print STDERR "valid: ",$doc-> is_valid(),"\n";    # would SIGSEGV too
print STDERR "done\n";                           # no way!

__END__

Thanks,

-- Petr
