Further debugging into transform ( kdelibs/kdoctools/xslt.cpp ) revealed that
the crash occurs in line 178 xsltFreeStylesheet(style_sheet).

According to SaroEngels even if the Q_WS_WIN && SIMPLE_XSLT part is not in
there it still crashes. I can verify this by checking the validity of the
xsltprocExternalLoader return values.

Since style_sheet is a valid style_sheet the remaining "Bug Source" is libxml2
itself.

I've reverted all our code patches in libxml2 and it still crashes. I've set
libxml2 to non threaded (which is not an option for kde but just for testing)
and it still crashes.

Until a better solution is found the enterprise5 configuration of meinproc will
include a patch delting that free. A memleak in a temporary process used during
build is better then an altogether instable buildsystem.
