compiler crash with order of evaluation for reordered named arguments

[metagn]

Nim Version

c3f64fb

Description

proc foo(a, b: int) =
  echo a
  echo b

proc main =
  foo(
    b = (let x = 123; 456),
    a = x)

main()

Works at top level, needs to be in a proc

Current Output

(8, 9) Error: internal error: expr: var not init x_520093701
