[BUG] Mojo process killed while instantiating a custom data type

[TheAbhilash23]

Bug description

The code i executed

from utils.variant import Variant from collections.optional import Optional

alias PrimitiveTypes = Variant[String, Int, Bool] alias PrimitiveJSONType = Optional[Variant[String, Int, Bool]] alias CompositeJSONType = Optional[Variant[List[PrimitiveJSONType], Dict[String, PrimitiveJSONType], List[Dict[String, PrimitiveJSONType]]]]

@value struct MultimorphicDict(Stringable):

var _dict: Dict[String, CompositeJSONType]


fn __init__(inout self):
    self._dict = Dict[String, CompositeJSONType]()
    


fn __str__(self: Self) -> String:
    return "Needs Implementation"

The compiler hangs and runs out of memory and then ultimately gets killed

Steps to reproduce

• Include relevant code snippet or link to code that did not work as expected.
• If applicable, add screenshots to help explain the problem.
• If using the Playground, name the pre-existing notebook that failed and the steps that led to failure.
• Include anything else that might help us debug the issue.
