[Freeswitch-users] Scaling Question

Mon Nov 3 18:57:01 PST 2008

What revision are you on because the line numbers of those errors don't
match up even slightly close?
Did you do something to disable building with debug symbols because the
current default is to build with them?
What platform are you on?

Could you try a clean build of the latest revision?
