(In reply to Andrew Pinski from comment #3)
> lambda are not considered an immediate context which is why func1 fails for

> Also unused template arguments for concepts are not taken into account so in
> this cases the lambdas for C2 are ignored. This is why GCC works (clang has
> a bug in this area; let me find that issue).

See PR 105615 and PR 102419.
