I don't think this is reliably OK. If you're not using Stopper
later in the function, and if there are no other references to
it, then the GC can collect it. It just has no obligation to
collect it, so minor differences like this might prevent that
from happening for particular compilers/options/versions.
I saw a thread on this forum named
'Why are so many programmers do not like GC'
or something like that.
After this adventure I would add my 5 cents:
because (sometimes, ok) it behaves absolutely
unpredictable, depending on operation order,
"particular compilers/options/versions" etc.
Nondeterminism in heap collection is a very common complaint, but
here we have data is that apparently on the stack that is
collected nondeterministically. I can't say I like that.
