Recently, I found myself in the following situation:
There is library software written in C which declares some externals
like:
struct METER m1;
struct METER m2;
[...]
static void OnChangemeter(struct METER *m)
{
if (m == &m1) ...
if (m == &m2) ...
}
Now the comparison of these pointers is UB in C
Why?
