[xml] Re: xmldocdump crash?

["Igor Zlatkovic" <igor zlatkovic com>]

Hi Andries,

please use the libxml mailing list for discussion about libxml, unless
things are private and/or confidential. I don't see anything of the sort in
your mail, so I'll take the freedom to copy this to the list.

The only thing I can think of is that you perhaps linked your app to the
runtime which is different to the one used by libxml. Try setting your
runtime to 'multithreaded dll' and see if things get any better.

By the way, if this really is the root of the problem, it is a perfect
example for the incompatibility of stdout between runtimes, a thing I posted
about five minutes ago. :-)

Ciao,
Igor
