I am trying to build the 2.0.1 distro on a Mountain Lion Mac OSX machine with gcc 4.2.1. I tried doing ./configure CFLAGS="-mmacosx-version-min=10.6" before doing my make dep and make, but when I run PJSUA on the Snow Leopard machine I am getting a segmentation fault. Has anyone run into anything like this and has any ideas? I tried looking through the mailing list but I didn't see anything about this. Thanks, Rebecca
