Axbx.mat is also attached with this bug report. This problem does not arise if
Ax were replaced by some other matrix, i.e., Ax\bx works just fine for most
matrices Ax.
octave run within gdb produces the following output:
octave:1> load "Axbx.mat"
octave:2> x = Ax \ bx
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00007fff5fc00000

I am running octave-3.6.2 compiled from source. The configure command was:
$ sudo ./configure LDFLAGS=-L/usr/local/lib/ -lmetis -lgfortran -lf2c
CFLAGS=-I/usr/local/include CPPFLAGS=-pthread -I/usr/local/include FF=gfortran
--with-blas=-ldotwrp -Wl,-framework -Wl,Accelerate --with-lapack=-ldotwrp
-Wl,-framework -Wl,Accelerate --disable-docs --without-hdf5 --without-opengl
and uname -a produces
Darwin zemme2.local 10.2.0 Darwin Kernel Version 10.2.0: Tue Nov 3 23:08:29
PST 2009; root:xnu-1486.2.11~3/RELEASE_I386 i386
I would greatly appreciate any help with this problem.
