In this specific case, most likely it's a stale register or
stack reference. One way I usually use to ensure such things is
to call a function that destroys the existing stack:
```d
void clobber()
{
int[2048] x;
}
```
Calling this function will clear out 2048x4 bytes of data to 0
on the stack.

Does it mean that if my function _func()_ is as following (say I
don't use clobber), I could keep a lot of memory for a very long
time (until the stack is fully erased by other function calls) ?
```
void func()
{
Foo[2048] x;
foreach(i; 0 .. 2048)
x[i] = new Foo;
}
```
