testcase
Now that I know what to look for I reduced the testcase again trying to make
sure to not introduce uninitialized uses in the process.
As far as I can tell the warning in the attached testcase is wrong.
First an optional is constructed, but _M_engaged is false since it doesn't hold
a value.
It is then moved, but move constructor checks __other._M_engaged, so the
temporary_buffer move constructor should never be called.
