I can reproduce the crash with the following:

  target triple = "arm64--"
  declare void @extfunc([4096 x i64]* byval %p)
  define void @func([4096 x i64]* %z) {
    %lvar = alloca [31 x i8]
    %v00 = load volatile [31 x i8], [31 x i8]* %lvar
    store volatile [31 x i8] %v00, [31 x i8]* %lvar
    call void @extfunc([4096 x i64]* byval %z)
    ret void
  }
