To point out the obvious: if ex.err says that result hasn't been assigned a
value, then it hasn't been. There are a couple possibilities:

1. The initialization is in a conditional statement that gets bypassed.

2. The execution order isn't what you expect, and you reach the test before
the initialization.

3. You are initializing a local variable and testing a global, or vice
versa. (I'm guessing this is what's happening to you).

I'd stick a trace before the initialization and test, to make sure they were
executing in order. If that doesn't work, reduce the code to a minimum and
post it - I'd love to see it.
