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."

Is this still an issue for others? It seems to be related to the compiler version, but maybe there are internal changes that make the issue moot? -- Ticket URL: <https://trac.macports.org/ticket/30627#comment:5> MacPorts <http://www.macports.org/> Ports system for Mac OS

FLTK(-devel) is @1.3.x-r9204; gcc45 is @4.5.3. This was a clean install, with only minimal other ports installed -- so, any port depending on the variants was installed using those variants. I did not get the mismatch dimensions crash. I'm wondering if the OP has the same variants for octave-devel, atlas, and qrupdate? That would certainly be an issue if not. -- Ticket URL: <https://trac.macports.org/ticket/30627#comment:7> MacPorts <http://www.macports.org/> Ports system for Mac OS
