Case closed.

[Bob W]

Thanks guys for your replies!

For anyone who had no time to check upon
my suspicions that D was producing something
'unexpected', here is a short explanation:

My sample program can be imagined as the
attempt to mark a freeway exit with an arrow
inside a car in order to find it later. Unfortunately
I was moving the car afterwards so the arrow
was pointing to ... (you guess).

As a result I have to admit that D did not
deserve any of my secret suspicions about
its stability in this respect.

At least I was careful enough not to use
the word 'bug' in any of my posts.   ;-)
