octave-devel crashes on mismatched matrix dimensions

[jmrosenstock@…]

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."
