The problem only affects Darwin/PPC and here are the unknown reasons:

Division by zero has an undefined result on PowerPC processors. The 
compiler has to emit extra code to assert that the divisor isn't zero.

Removing -fno-trapping-math or adding -fnon-call-exceptions options 
might or might not convince GCC to do so (have no PPC machine to try).

If that won't help seems there's nothing we can do about it.
