Compiler segfaults when passing static parameter to non static macro parameter

[ire4ever1190]

Description

This code breaks using devel compiler

!nim c

import std/macros

macro foo(a: openArray[string] = []): string =
  echo a # Segfault doesn't happen if this is removed
  newLit ""

proc bar(a: static[openArray[string]] = []) =
  const tmp = foo(a)

assert compiles(bar())

GDB shows it segfaulting in ORC

🤖 Bug found in 52 minutes bisecting 326 commits at 6 commits per second

[ire4ever1190]

When finding a workaround I found the bug wasn't specific to openArray. Seemed to be passing a static parameter to a non static parameter caused the segfault

import std/macros

macro foo(a: int): int =  # This also needs to be invalid
  echo a.intVal

proc bar(a: static[int]) =
  const tmp = foo(a)

echo compiles(bar(1)) # Only crashes when `compiles` is used?

Not too sure why my bisect found a different commit. Haven't read into how the action works but I had to bisect different to the normal process since I needed to do a full ./koch boot because if I just used ./koch temp it would always fail (since it would always compile with a version of the compiler containing the big)

[ringabout]

These automatic regression testings are not accurate. I will make a round of bisect locally

[ringabout]

Now, why the former bisects are in vain. We must boot a compiler, which is the issue. I will do one more

[ringabout]

Indeed, 8f5b90f88 is the cause. I have finally confirmed
