That sounds strange to me.
void f()
{
char* ptr = 0;
}
# g++ -Wall f.cpp -c
f.cpp: In function 'void f()':
f.cpp:3:8: warning: unused variable 'ptr' [-Wunused-variable]
I.e. all warnings turned on, but nothing bad is said about 0 assigned to
pointer.
And that's correct, cause in classic C++ book from Stroustrup it's
explicitly mentioned that 0 is specific constant which may be converted
to any simple type.
