            Bug ID: 93895
           Summary: ICE (segmentation fault) in use of __is_constructible
                    intrinsic
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

Created attachment 47892
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=47892&action=edit
result of creduce on the error

Happens with trunk. Compile the attached repro.cpp.i with:

  g++ -std=c++2a -xc++ -c repro.cpp.i

The attached file is the result of creduce which sadly made the code invalid,
but the original ICE happened on valid code.
