           Summary: [REG2.080.0-beta.1] Array.length setter segfaults for
                    payloads with indirections

          Severity: regression
          Priority: P1

import std.container.array;

struct S { void* p; }
void main()
{
    Array!S a;
    a.length = 10; // segfault
}

The code uses `_payload.sizeof` instead of `_payload.length*T.sizeof`
