The gnat binary in gcc-4.9.0-x86_64-apple-darwin13-2014-1.tar.bz2 is working. Did not know that gnatchop -h is causing a segmentation fault though. You see, I am new to Ada. The (Segmentation fault: 11) error takes the fun away, unfortunately.

Solution:

Configure GCC with --with-host-libstdcxx=-lstdc++. I also tested --with-host-libstdcxx=/usr/lib/libstdc++.6.dylib and that works too.

I read about --with-host-libstdcxx at https://gcc.gnu.org/install/configure.html. That did it. The gnat binaries are working as expected even when passing an unknown command (i.e. gnat -v or gnatchop -h).
