 I reported this to octave:
 https://savannah.gnu.org/bugs/index.php?33943

 They think something with catching exceptions isn't right with the
 macports configuration, perhaps related to exception handling.

 "The xgemm function is part of Octave (liboctave/dMatrix.cc). When it
 detects a dimension mismatch, it calls gripe_nonconformant (liboctave/lo-
 array-gripes.cc). That function calls an error handler using the function
 pointer current_liboctave_error_with_id_handler. Normally, that is set to
 lo_error_with_id_handler (set in the function initialize_error_handlers in
 src/octave.cc). That function ultimately calls
 octave_throw_execution_exception (libcruft/misc/quit.cc) which ultimately
 throws a C++ exception which should be caught in the main_loop function
 (src/toplev.cc). I'd guess the abort is happening because the exception is
 not caught as it should be."

 GNU Octave, version 3.4.2
 Octave was configured for "i386-apple-darwin9.8.0".
