void for_each(_Function __f)
void trim(SequenceT& Input, const locale& Loc=locale());
I don't know if this is valid or not but guess what ICC also ICEs on this testcase too.
Confirmed, this is was just a split out.
I think this is a duplicate of PR 24602.
The only difference is the missing copy-ctor here.
Since Nathan's patch for PR32839 we get the same error message for PR24602
as for PR24606. This really looks like a duplicate.
