I'm trying to learn about stack base overflow and write a simple code to exploit stack. But somehow it doesn't work at all but showing only Abort trap on my machine (mac os leopard)

I guess Mac os treats overflow differently, it won't allow me to overwrite memory through c code. for example,

strcpy(buffer, input) // lets say char buffer[6] but input is 7 bytes

on Linux machine, this code successfully overwrite next stack, but prevented on mac os (Abort trap)

Anyone know how to perform a simple stack-base overflow on mac machine?
