compiler crash on simple macro

[krux02]

import macros

  let procDef = quote do:
    proc foo(): void =
      echo "bar"

  result = newStmtList(
    arg, procDef
  )

  echo result.repr

iterator bar(): int {.foobar.} =
  discard

Seems to be related to iterator as switching to proc stops this crash.

[metagn]

doing

foobar:
  iterator bar(): int =
    discard

also seems to work

[krux02]

@hlaaftana Yes I forgot to mention it here:

Even though these two statements are supposed to mean the same, one of them crashes the compiler, the other one works fine:

iterator bar(): int {.foobar.} =
  discard

foobar:
  iterator bar(): int =
    discard

oh, thanks a lot
