[xslt] Segfault while copying a nodeset (document)

[Raphael Hertzog <rhertzog hrnet fr>]

Hi,

here's another segfault. Attached are the files used to generate it.
Just put them in a dir and launch :
$ xsltproc test.xsl test.xml

The segfault itself happens in libxml but the root problem comes from
libxslt I think. Again the problem is in the way to manage DTD
information when copying nodes ...

Should we copy DTD nodes when you launch :
<xsl:copy-of select="document('test2.xml')"/>

I think that we shouldn't. But maybe other can think of a use of such a
feature ?

I may have a trivial patch but I need to test it later before submitting
it ...

Here's the backtrace :
#0  xmlStrchr (str=0x11 <Address 0x11 out of bounds>, val=34) at
parser.c:1240
