            Bug ID: 111075
           Summary: ICE on g++.dg/torture/tail-padding1.C on darwin
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: fxcoudert at gcc dot gnu.org
  Target Milestone: ---

ICE on valid C++ code, reduced from the test failure of
g++.dg/torture/tail-padding1.C observed on x86_64-apple-darwin20 (see for
example at
https://gcc.gnu.org/pipermail/gcc-testresults/2023-August/793205.html):

$ cat z.C
struct X { ~X() {} int n; char d; };
struct Y { Y(); char c[3]; };
struct Z : X, virtual Y { Z(); };

X f() { X nrvo; __builtin_memset(&nrvo, 0, sizeof(X)); return nrvo; }
Z::Z() : Y(), X(f()) {}

$ /tmp/irun/bin/g++ -Os z.C   
z.C: In copy constructor ‘constexpr X::X(const X&)’:
z.C:1:8: internal compiler error: in cxx_eval_call_expression, at
cp/constexpr.cc:2918
    1 | struct X { ~X() {} int n; char d; };
      |        ^
