Re: [ MP2] startup problem with XML::LibXML

[pascal barbedor]

hi

what version of libxml2 should I use 
?


I tried to compile version 
1.52
against versions libxml2-2.5.1 
precompiled binary from xmlsoft

test failed with segfault

t\08findnodes.t list of failed 
6-18
t\13dtd.t 
list of failed 11-12

if I nmake install nevertheless , apache 
startup problem remains.


before that I tried to compile XML::LibXML 
1.52 against a slightly prior version of libxml2
all test successful but the problem with 
apache startup remains.

I also found XML::LibXML had problems on Win32 against 
libxml2-2.5.1.

I found that libxml2-2.4.26 worked OK with XML::LibXML's tests,
but not latter versions (eg, 2.4.30). Christian Glahn, in a
recent post on the perl-xml mailing list, also saw such problems,
so it's not a Windows specific thing.

I just tried making up a static XML::LibXML/XML::LibXSLT,
to see if that would help any, but this still causes problems
when used in a startup file.

[ MP2] startup problem with XML::LibXML

[pascal barbedor]

PROBLEM :
APACHE SEGFAULT WITH XML::LibXML on 
WIN32

I use all in one perl + apache + modperl2 RK 
binaries
but I replace c:\perl\bin\perl58.dll with 
perl58.dll obtained after separately(and succesfully) compiling perl with vc6 
DEBUG so that I get symbols in 
perl58.dll
so the call stack gives line number in source (see 
below)
everything works normally as far as I tried 
prepared scripts in RK distribution, but my test.pm makes an APACHE 
SEGFAULT
when used from startup.pl.

mytest.pm program
---
package mytest;
use warnings;
use XML::LibXML();
use strict;
our 
$test=XML::LibXML-new-parse_string("?xml version='1.0' 
encoding='iso-8859-1' ?doc/doc");
print $test-toString();
1;
-
perl mytest.pm output ok
USE from a regular CGI WORKS
USE from a registry CGI works
USE from a modperl handler (mason) 
works

!!! use test(); from startup.pl output ok BUT 
produces just after apache segfault


thanks 
pascal

What version of XML::LibXML? Try version 1.52, not 1.53 which is very 
buggy.
