How many lines does one need to break VCS? Not much.

```

module tb;
logic a = 0;
logic b = 0;
logic bb = 0;
logic [1:0] c;

function automatic logic foo(logic x, logic y);
return x && y;
endfunction

always_comb begin
c = 0;
unique0 if (a) begin
c = 1;
end else if (foo(b, bb)) begin
c = 2;
end else begin
c = 3;
end
end

initial begin
#1;
a <= 1;
b <= 0;
bb <= 0;
#1;
a <= 0;
b <= 1;
bb <= 1;
#1;
end

initial begin
$monitor("%t : %b %b %b %0d", $time(), a, b, bb, c);
end

endmodule

```

Output:
