From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040808 Firefox/0.9.3 Description of problem: I'm working on a large DocBook project that has been compiling successfully until today. Last night I upgraded libxml2 through up2date and now when I run xsltproc against my project, it segfaults. I've not been able to find any other diagnostic information on xsltproc. Perhaps I don't know where to look, or what the right command switches should be. Rolling back libxml2 to rel. 2.6.8-1 corrects the problem. Version-Release number of selected component (if applicable): 2.6.15-2 How reproducible: Always Steps to Reproduce: 1.Update FC2 to the latest libxml2 (libxml2-2.6.15-2.i386.rpm) 2.[ken@johngalt HeadStart]$ xsltproc custom-html.xsl WebCAF-book.xml 3.Segmentation fault Actual Results: Segmentation fault Expected Results: Writing pr01s02.html for section(intro_06) Writing pr01s03.html for section(intro_07) [...] Writing go01.html for glossary Writing index.html for book Additional info: You can find the source to my book by snagging all of the .xml and .xsl files in www.webcaf.com/manual/rsync/
Can you try two things: 1/ get back to libxml2-2.6.15 , run the command xsltproc -v custom-html.xsl WebCAF-book.xml and paste the last few lines before it hangs 2/ then upgrade to libxslt-1.1.11 (you may need to also update the -python and -devel if they are installed locally) from ftp://xmlsoft.org/ and see if it still hangs. Getting those informations would help me diagnose and possibly reproduce the problem, as well as xsltproc --version output. I will look at it before next week, thanks for the report ! Daniel
I looked at http://www.webcaf.com/manual/rsync/ , I only get a web page but not a directory listing, hence I'm unable to guess the filenames. Could you assemble all the .xsl and .xml needed to run a session into a tar.gz and put it on-line ? I need them to reproduce the problem. thanks, Daniel

There is an index.html file at the URL I gave earlier, so using a Web browser to access it is probably a lost cause. Since it appears that the bug is on its way to being resolved, I won't upload a .tar.gz at this time. Please let me know if you still need it later.
I had the same problem and 1.1.11 from rawhide fixed it.
Okay after some testing and analysis based on Markus's input, the bug is related to exslt:node-set extension handling in a given use in the DocBook stylesheet doing chunking. This is deep voodoo and the way that extension is handled was cleaned bu since the FC2 area in both libxml2 and libxslt. As a result an unexpected and hard to detect dependancy was made between both modules. The simplest and best tested fix is to push an update of libxslt at the level of libxml2 used, i.e. libxslt-1.1.12, so I will try to get a fc2 update libxslt-1.1.12-2 out during the week-end, thanks for the report and feedback, Daniel
libxslt-1.1.12-2 has been pushed to fc2 updates, Daniel
