Bug ID: 97814
Summary: Copy constructor deletion not recognized in
initialization list with -std=c++17
Product: gcc
Version: 9.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: caparson at uwaterloo dot ca
Target Milestone: ---

A short 12 line code snippet that when compiled reproduces the bug.
When compiling the attached program with the command "gcc copyConstruct.cc
-std=c++17" it does not produce the following error:
copyConstruct.cc:11:20: error: use of deleted function ‘S::S(S&&)’
11 | C() : lock(S(1)) {}
| ^
copyConstruct.cc:4:5: note: declared here
4 | S( S && ) = delete;
| ^
But it does with the command "gcc copyConstruct.cc -std=c++14".
It seems to not recognize that the copy constructor is deleted when it is used
in an initializer list.
