[xslt] libxslt seg faults when reporting error about missing namespace decl.

[Luca Padovani <lpadovan cs unibo it>]

Hi,

the attached stylesheet (just 4 lines of XSLT) causes xsltproc to seg
fault:

> xsltproc crash.xsl
> Segmentation fault

> xsltproc --version
> Using libxml 20609, libxslt 10106 and libexslt 804
> xsltproc was compiled against libxml 20609, libxslt 10106 and libexslt
> 804
> libxslt 10106 was compiled against libxml 20609
> libexslt 804 was compiled against libxml 20609

It seems like the problem occurs when libxslt tries to report an error
about a prefix for which there is no declaration.

Should I submit this to the bug tracking system?

Cheers,
