[Bug gcov/profile/23052] New: return of class object sometimes reported as uncovered code

["jbuck at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

With the attached test case, do

% g++ -ftest-coverage -fprofile-arcs covbug.cpp -o covbug
% ./covbug
% gcov covbug.cpp

There will be two lines flagged as uncovered:

% grep '####' covbug.cpp.gcov
    #####:   29:    m_bits = new unsigned[nw];
    #####:   37:  return result;

The first is expected, the second is wrong.  I repeatedly see
errors of this type, where a return of a class object is flagged as
not covered.  Either a "-" (indicating that no code is present) or an
execution count would be acceptable, but putting out ##### indicating
uncovered source code is a bug.
