Hi,
I don't dispute your solution, but I'm no friend with
the author of XMLSec a will hardly pursue him to do that :) And I want
to use the tool. Right now I'm content with the hack I mention in the previous
post, but I still think that's ugly.

I don't understand libxml2 code that much to say that
using an intermediate file will solve it. What seemed to me is, that the
int buffer counter I mentioned before is file-specific, thus it would overflow
after 2GB write whether the destination is memory or a file. Nobody has
disproved this yet, so are you sure I understand it wrong?

Staying with the topic - is it possible for you to
write a simple test to write some >2GB file with libxml2 the way it
should be properly done (what is it anyway?) and check that 'xmlOutputBufferClose()
' returns a positive number? That should probably
prove it.

Thanks,
Vit
