[xslt] Segfault in xsltGenericDebug (vfprintf?)

[Fredrik Wahl <FRWAH orangedk com>]

I get a segfault in xsltGenericDebug when package is compiled with
--with-debug (default) and the xml is larger than appr. 50k. 
It's a large <![CDATA[-section with HTML (and stuff) which gets printed by a
<xsl:value-of.

Is this due to limitations in vfprintf?

Tested with libxslt 0.11.0 (and now 0.12.0) on Progeny Debian and FreeBSD
4.2.
