Subject: LibXSLT coredumps after transform() called on Solaris 5.10
Hi, I've installed XML::LibXSLT-1.63 and XML::LibXML-1.65 on Solaris and can successfully transform XML documents through XSL stylesheets. However, once XML::LibXSLT::transform() has been called, Perl coredumps when it tries to dispose of the XML parser and the XSLT object (usually when exiting the scope where they have been instanciated). This happens both in command line and under mod_perl. I've attached a simple test script (based on and the backtrace extracted with gdb from the corefile it produced. Can you reproduce the coredump with this test script or is it something I did wrong during XML-LibXSLT's installation? Here is a few extra information on my machine: 'uname -a' returned 'SunOS 5.10 Generic_125100-10 sun4v sparc SUNW,Sun-Fire-T200 Solaris' 'perl -v' returned 'v5.8.6 for sun4-solaris' I've also reported this issue in CPAN forums: Thank you in advance

I cannot reproduce this problem under Linux. Valgrind (a tool that reveals memory-related problems) indicate nothing wrong when I run your sample. You didn't indicate the version of libxslt you have installed. Please upgrade to the latest libxml2 and libxslt from and try again. Please reopen the bug if you can reproduce the problem with the latest versions. -- Petr
