No, this is a terrible idea.  Apart from the coding style thing all
you're doing here is just ensuring that a value is set in the variable
without any analysis saying that this is a sensible value to set or that
the compiler hasn't spotted a genuine issue.

There's also the possibility that the compiler is just buggy...
