I'm not experienced enough to really reply to this, but:
Something sticks to an old (Collection) incarnation of X.
If you change your code like this:
| x |
x := OrderedCollection new.
x add: 'blue'.
x do: [:a | Transcript show: a; cr]
making x local to the running code, the problem goes away.
First I thought the doIt would stick to x but
Smalltalk forgetDoIts
didn't help either.
So now I'm as curious as you to a reply of someone who really knows
:-)
Cheers
