Error: internal error: expr: var not init a_536870917 with non-quasiquoted variable in macro

[tersec]

Description

import std/macros

macro p(): untyped =
  result = newStmtList()
  var a: int
  result.add quote do:
    discard a

p()

It's true that using, e.g.,

  discard `a`

fixes this, and this isn't meant to be correct-as-such-code. The point here is the Nim compiler internal error.
