Bug ID: 98841
Summary: wrong ‘operator=’ should return a reference to ‘*this’
[-Weffc++]
Product: gcc
Version: 10.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: o.mandel at menlosystems dot com
Target Milestone: ---

Console output of version 8.3.0
I get unexpected warnings about "'operator=' should return a reference to
'*this' [-Weffc++]".
This happens for at least versions 8.3.0 and 10.2.0 of g++. The output of the
following command is attached for both versions:
g++ -v -save-temps -Weffc++ -c t.cpp
In the minimal demo used here this only happens for a template member function,
but in larger code it can also be observed for a plain member function: see
e.g. https://github.com/jbeder/yaml-cpp/issues/970
This might be the same issue as mentioned in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84364#c9 (why the comment asked
for that ticket to be reopened)?
