In other words, env:powerpc/memprot do not give me any difference for crashing programms ?
It does make a difference. It causes more programs to crash.
With memory protection every forbidden memory access will cause an exception (crash).
Without memory protection illegal memory accesses are not trapped and do not crash. But they might cause other unpredictable troubles. For example graphics corruption on the Workbench or in other programs or random crashes of otherwise stable programs.
