wrong Error: cannot generate VM code depending on unrelated code

[timotheecour]

very strange bug: we get a CT error Error: cannot generate VM code for valid code, and the CT error disappears when commenting out or making private an unrelated constant (or when using currentPkgDir2() instead of currentPkgDir2)

D20191124T182358

Example

nim c t0796.nim

t0796.nim:

import t0796b
const s0 = currentPkgDir2

t0796b.nim:

import std/macros
const getPrivate3_tmp* = 0
const foobar1* = 0 # comment this or make private and it'll compile fine
macro foobar4*(): untyped =
  newLit "abc"
template currentPkgDir2*: string = foobar4()
macro currentPkgDir2*(dir: string): untyped =
  newLit "abc2"

Current Output

t0796.nim(22, 12) Error: cannot generate VM code for currentPkgDir2

Expected Output

should compile

Additional Information

fails on all versions of nim, including recent devel f22d3c7

[metagn]

Now gives

t0796.nim(2, 12) Error: ambiguous identifier: 'currentPkgDir2' -- use one of the following:
  t0796b.currentPkgDir2: template (): string
  t0796b.currentPkgDir2: macro (dir: string): untyped{.noSideEffect, gcsafe.}

Is this fine?
