            Bug ID: 95291
           Summary: ICE
           Product: gcc
           Version: 10.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: wouter at voti dot nl
  Target Milestone: ---

The compiler ICE's on this code. I used the 10.0.1 on windows, but the 10.1=
.0
on compiler explorer gives the same ICE. Options: g++ --std=3Dc++20

https://godbolt.org/z/As6Rm7

template< typename T =3D int >
class xy { };=20

template< xy _size >
struct window_root { };

template< typename minion >
struct flip_horizontally : window_root< minion::size >{ };=
