Very handy.

The result might not quite be what you expect with all C++ compilers, 
though:

———
$ clang -Wall test.cpp
test.cpp:2:5: warning: indirection of non-volatile null pointer will be 
deleted, not trap [-Wnull-dereference]
    *(char*)0=0;
    ^~~~~~~~~
test.cpp:2:5: note: consider using __builtin_trap() or qualifying 
pointer with 'volatile'
