xsltproc crashdump

[Christian Holtje]

Binary package hint: xsltproc

I think the cause was creating func:function (using exslt) with TWO func:result nodes...

Example (untested):
<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:func="http://exslt.org/functions"
                extension-element-prefixes="func"
>
  <xsl:output method="xml" indent="yes"/>

<func:function name="foo">
  <func:result select="'bar'"/>
  <func:result select="'bar'"/>
</func:function>

<xsl:template match="/">
  <node>
    <xsl:value-of select="foo()"/>
  </node>
</xsl:template>

</xsl:stylesheet>

Ciao!

Forgot to attach the coredump.

Ciao!

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.

It still does a core dump:
$ xsltproc launchpad-35439.xsl empty.xml
exsltFuncResultElem: only xsl:fallback is allowed to follow func:result
zsh: segmentation fault xsltproc launchpad-35439.xsl empty.xml

I have attached the correct XSL for this.

Note, it still shows the correct error, but it shouldn't segfault.

What version of xsltproc are you using? I just tried on Intrepid with

xsltproc:
  Installed: 1.1.24-1ubuntu1

and don't get this error anymore.

[Christian Holtje (docwhat)]

ii libxslt1.1 1.1.22-1ubuntu XSLT processing library - runtime library
ii xsltproc 1.1.22-1ubuntu XSLT command line processor

Ubuntu Hardy Heron.

What is the output from running this in Intrepid?

[Andreas Moog (ampelbein)]

andreas@Callypso:~/Desktop$ xsltproc launchpad-35439.xsl empty.xml
exsltFuncResultElem: only xsl:fallback is allowed to follow func:result
warning: failed to load external entity "empty.xml"
unable to parse empty.xml

Andreas:

You have to create the empty xml node. You can use launchpad-35439.xsl if you want or you can greate an empty.xml file:

* empty.xml would be something like:
<xml/>

* The commandline to use launchpad-35439.xsl is:
xsltproc launchpad-35439 launchpad-35439.xsl

Without the xml file, I don't get a segfault either.

Ciao!

[Andreas Moog (ampelbein)]

Okay, now i can reproduce the bug. I'm getting a segfault, too. Setting this to confirmed for developers to start working on it. Thanks for the report.
