sizeof array with static N crash in type section

[mratsim]

The following crashes in a type section, removing sizeof(array[N, ptr T]) avoids the crash.

const CacheLineSize = 128

type Foo = object
  x: int

static:
  echo(CacheLineSize - sizeof(array[10, ptr Foo]) - sizeof(int) - sizeof(pointer))
  echo "Successful static compute"

type
  Stack*[N: static int, T: object] = object
    pad: array[CacheLineSize - sizeof(array[N, ptr T]) - sizeof(int) - sizeof(pointer), byte]
    stack: array[N, ptr T]
    len*: int
    rawMem: ptr array[N, T]

echo "Hello world"

The error message points to int128

32
Successful static compute
fatal.nim(39)            sysFatal
Error: unhandled exception: int128.nim(330, 11) `false` overflow [AssertionError]

Replacing N by 10 works so static is important.

Workaround: use N * sizeof(ptr T) instead of sizeof(array[N, ptr T])
