Answer 1

The version of GDB you're using (Apple's version) doesn't seem to support the newer features of the compiler you installed from macports.

The error message is reporting that GDB doesn't understand some of the debugging information it's encountered in the program. The debugging information it has shown is a C++11 feature.

The solution is to either upgrade to a newer GDB (probably from macports if there's one there), not use the features that GDB doesn't understand, or accept that the version of GDB you have won't be able to understand this.
