You could assert that the set is not empty here
auto it = s_minus_sq.begin();before dereferencing it.Yeah, that's working thanks!
But I think that the condition never arrives at which s_minus_sq.size() is 0 and control is at else if . That's why I haven't checked that condition.
Can you tell me what lead you to that?
The Checker Diagnostics looks like access to "bad" memory, and I did not see any other line of suspicious code.
