Moving object creation outside of the if statement works as intended.

struct Thing
{
this(int* i) { ptr = i; (*ptr)++; }
~this() { (*ptr)--; }
T opCast(T:bool)() { return false; }
int* ptr;
}

Thing makeThing(int* p)
{
return Thing(p);
}

void main()
{
int i;
{
auto t = makeThing();
if(t)
{
import std.stdio;
writeln("hello?");
}
}
assert(i == 0);
}

Observed output:
