Dear all,

I provision the server and then this crash occurs never now and then.

I try a few times and this crash goes away but I want to know the
technical way to solve it. ;)

Here is the complete log.

Not really sure. Is it possible to get a debug build, so the backtrace
contains the line numbers where the crash is occuring?

I think I solved it by installing the latest talloc library.

But now that you mention it I am curious to know how to create a debug
build with openchange. Do you mean "CFLAGS+=-g" in Makefile?

Thanks.
