xsltproc seg faults (solved)

Message

Hello all,

I'm having problems using xsltproc to generate docbook documents. No matter what I do xsltproc always seg faults on me. I'm writing some XML DocBook, and according to xmllint it is all well-formed. I've done some searches and tried re-emerging libxslt and docbook-xml-dtd after recreating my xml catalog, but no luck.

I've also noticed a number of Gnome packages that aren't able to install docs because xsltproc is seg faulting, so it seems this is a fairly common problem, but I've yet to find a solution.

The output of xsltproc --version is

Code: Select all

Using libxml 20615, libxslt 10108 and libexslt 806
xsltproc was compiled against libxml 20615, libxslt 10108 and libexslt 806
libxslt 10108 was compiled against libxml 20615
libexslt 806 was compiled against libxml 20615

Here's the file (greatly cut down) that causes the error:

Code: Select all

Any help would be greatly appreciated,

Segfault or killed due to an out of memory condition?

It's definitely a seg fault. I watched memory and it doesn't even come close to filling memory, at the max xsltproc uses 48 Mb, and even with everything else I don't get near the 320 Mb I've got installed. "Segmentation fault" actually gets output.

I've done a little research and it seems that this happens for XHTML, HTMLHelp and JavaHelp output formats. The HTML output works, but I get a message

Code: Select all

free(): invalid pointer 0xae55020!

at the end of the run. Formatting objects output seems to work fine.

Regards,
Jay

It looks like the problem solved itself when I upgraded to libxslt-1.1.9-r1.
