Segmentation fault on illegal recursion in generic types

[haxscramper]

trafficstars

Generic type with illegal recursion causes segmentation fault in compiler instead of illegal recursion error.

Example

type
  Test[T] = object
    f2: Test[T]

let t = Test[int]()

Current Output

Segmentation fault (core dumped)

Expected Output

Error: illegal recursion in type 'Test'
