The problem I see here is that the statements in the if and else parts
have their own scopes which would exit right away so
FreeDevice/FreeResource would also get called right away, not at the
end of the function scope.

My assumption here is that this is just a normal if statement and that
~{...} is treated as a statement that adds code to be executed to the
end of the current scope.
