            Bug ID: 102866
           Summary: Unexpected error on variadic forwarding
           Product: gcc
           Version: 11.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: benni.probst at gmx dot de
  Target Milestone: ---

Created attachment 51640
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=51640&action=edit
A multi variant data container

I changed a push function to determine between containers that can execute
push_back and those who dont. The original line was just this->data =
this->create(args..., this->data); instead of the compile switch. At this point
the error occurred. The key is line 83 and 101

Sources cannot be uploaded because exe file is 1 Gigabyte in size
