Subject:

Stack Smash on Mandriva Cooker with perl-5.10.0-13mdv2008.1

The link http://xrl.us/bke4t points to an svn directory which contains a Module-Build-based module which uses XML-LibXSLT. On Mandriva Cooker I'm getting the following problem: <<<<<<<<<<<<<<<<< shlomi:$module$ perl t/to-xhtml.t 1..1 *** stack smashing detected ***: perl terminated ======= Backtrace: =========

Is there any progress on this bug? It seems to occur with a vanilla perl-5.10.0 too. And it stalls the release of this module https://svn.berlios.de/svnroot/repos/web-cpan/XML-Grammar-Fortune/ and heavily complicates my home-site's build process. Whatever happens, Perl should not segfault. Regards, Shlomi Fish

Hi Shlomi, I cannot provide any support for rpm packages, that's problem for the distributors. Did you try compiling CPAN versions of XML-LibXML/XSLT-1.66? If you say you tried vanilla perl-5.10, did you recompile the XML-LibX* packages? Can you run valgrind on your test: valgrind perl -Mblib t/to-xhtml.t and post the output? You should also post the output of perl -V, and indicate the versions of libxml2 and libxslt used (and maybe also try vanilla ones from xmlsoft.org). I tried your test with CPAN 1.66-versions on openSUSE 11 (also perl-5.10), and got no segfault at all; also, no error was reported by valgrind. This does not prove anything, since many things may be different between my and your configuration, but it's up to you to do some more testing. I'll try a vanilla perl-5.10, since so far I used vendor's, which says Compile-time options: DEBUGGING MULTIPLICITY PERL_DONT_CREATE_GVSV PERL_IMPLICIT_CONTEXT PERL_MALLOC_WRAP PERL_TRACK_MEMPOOL PERL_USE_SAFE_PUTENV USE_64_BIT_ALL USE_64_BIT_INT USE_ITHREADS USE_LARGE_FILES USE_PERLIO USE_REENTRANT_API Instead of a segfault, I got a usual failure, probably because your test is not correct. t/to-xhtml........NOK 1/1 # Failed test 'Testing for Good XSLTing of 'irc-conversation-4-several-convos'' # at t/to-xhtml.t line 52.

OK! Vanilla perl-5.10.0 (installed under a different prefix) with a self-compiled version of XML-LibXSLT works perfectly fine. I guess it's a problem with Mandriva somewhere. Show quoted text

since this was Mandriva only problem, I'm closing the bug for now.
