Discussion:

In 31.12.13.4 [fs.op.copy]/8 the final bullet says "Otherwise, no effects" which implies there is no call to ec.clear() if nothing happens, nor any error condition, is that right?

[2016-06 Oulu]

Moved to P0/Ready during issues prioritization.

Friday: status to Immediate

Proposed resolution:

Change 31.12.13.4 [fs.op.copy]/8 as indicated:

Otherwise no effects. For the signature with argument ec, ec.clear().
