<div>
<pre>Using the static analyzer from the checker-270 build for MacOSX on the
following
C++ source:
============================
void set_x(void *&);
int foo(void)
{
int *x = 0;
set_x((void *&)x);
return *x;
}
============================
results in:
warning: Dereference of null pointer (loaded from variable 'x')
This doesn't happen if the "void" is replaced by "int".</pre>
