--- Comment #6 from Frédéric <ufospoke at gmail.com> ---
OK, I went to the end of this and I am sorry to have disturbed you but it seems
that I was wrong. The thing is that in the same function I had multiple lambdas
referring to a constexpr std::size_t. And for some of them I could remove the
capture and not for the others. So the warning was related to one of the
lambda, and I tried to remove all captures so it did not work.

I now understand that if a lambda uses a constexpr variable in a call with a
const reference, the constexpr must be capture to have a reference at the time
of the call where the reference to the original variable is not accessible.

Thanks for your help.
