            Bug ID: 103563
           Summary: ostream operator<< resolved to variant containing type
                    resulting in stack overflow
           Product: gcc
           Version: 11.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: samuel.hangouet at gmail dot com
  Target Milestone: ---

Created attachment 51928
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=51928&action=edit
Minimal test case.

$ g++-11 --version
g++-11 (Ubuntu 11.1.0-1ubuntu1~20.04) 11.1.0
(...)
$ g++-11 -std=c++2a test.cpp -o test
$ ./test
Segmentation fault (core dumped)

In my opinion, this file should not compile as no operator<< is provided for
custom type V. 

Instead, the operator<< taking the variant which contains V is called,
resulting in stack overflow at runtime.
