method call syntax in nkRecWhen condition gives SIGSEGV

I noticed this while working on #14709

Example

when true:
  #[
  SIGSEGV: Illegal storage access. (Attempt to read from nil?)
  ]#
  type Foo[T] = object
    x1: int
    when T.sizeof == 4: discard # SIGSEGV
    # when sizeof(T) == 4: discard # ok
  let t = Foo[float](x1: 1)

Current Output

SIGSEGV

Expected Output

works
