Indeed, I get this too. This looks like a crash inside some atlas 
function, as the gdb output shows (the CrashReporter output is even less 
helpful):

octave:2> b=a'*a;

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: 13 at address: 0x00000000
[Switching to process 24424 thread 0x1003]
0x028c1391 in ATL_dupMBmm0_6_0_b0 ()
(gdb) bt
#0  0x028c1391 in ATL_dupMBmm0_6_0_b0 ()
#1  0x057bda20 in ?? ()
Cannot access memory at address 0x502

No idea how to debug this.
