            Bug ID: 102123
           Summary: Internal Compiler Error occurs during template
                    deduction in use with templates as template parameters
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: friedkeenan at protonmail dot com
  Target Milestone: ---

Minimal example: https://godbolt.org/z/P86MY1ccz

Compiles fine with clang. Compiles with gcc if you specify `Test<int>`, though
the deduction guide should make them equivalent. Possibly related to Bug 93425
