                    the ctor is separated from its declaration.
    Classification: Unclassified

            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++

Minimal example

In certain conditions if the definition of the ctor separated from its
declaration it generates an compiler error.

I created a minimal example. The original code is from Boost.Move.
Error:
testfull.cpp:16:1: error: prototype for ‘movable::movable(rv<movable>&)’ does
not match any in class ‘movable’
testfull.cpp:5:7: error: candidates are: movable::movable(const movable&)
testfull.cpp:13:5: error:                 movable::movable(rv<movable>&)


If the ctor definition is inside the class the code compiles.

The same can happen with the assignment operator as visible here:
