RE: let binding with c

Hi Manuel,
I will try to sort out a small test case; 
but actually I am sure about the exact and minimum conditions that raise the issue.
If few lines can illustrate it, then that may be manageable.
Thanks for your support.
Regards,
Michel.

Dear Michel,

This should work, normally. I cannot think about an obvious reason for this not to work. Could you give us some additional context? Would you have an actual code excerpt that illustrates the problem?
