<pre>Save this snippet as delete_void.cpp
int main() {
void *a=new char[100];
delete [] a;
return 0;
}
Then execute:
$ clang++ delete_void.cpp
delete_void.cpp:3:2: warning: cannot delete expression with pointer-to-'void'
type 'void *'
delete [] a;
^ ~
1 warning generated.
There is a warning, but there is no -W flag, so we cannot force it into error
and thus automatically prevent such bugs creeping in the code-base.
Tested with both 3.4 and 3.5.</pre>
