Re: [Iaxclient-devel] Strange fatal issue with attempted native transfer behind same NAT...

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

OK, I just applied a fix from Bill Doll.

Those of you on the -cvs list will see it's pretty obvious, if you know  
where it is :) (we were dereferencing a pointer, then assigning it to a  
pointer.  That never works).

Steve Uhler:  I guess you haven't used transfer, but can you take a  
look at the assignment of the possibly unaligned pointer to the  
apparent_addr ie?
