Error: internal error: genMagicExpr: mDup when using arrayWith with some types.

[Archargelod]

Description

Procedure withArray, when used with any types except int and string as first argument (I tested int32, int64, uint, uint8, char), crashes the compiler:

let
  a: int = 100
# a: string = "nim"
  b: int32 = 200'i32
# b: char = 'c'
# b: uint = 300'u

let
  x = arrayWith(a, 8) # compiles
  y = arrayWith(b, 8) # internal error
# y = arrayWith(14, 8) # integer literal also results in a crash

echo x
echo y
