Segmentation fault when omitting optional Hill climb pass parameters

[ffraenz]

When running the following query, a segmentation fault occurs:

{
  "$schema": "../schemas/query.json",
  "alphabet": "abcdefghijklmnopqrstuvwxyz",
  "ciphertext": "hello world",
  "space": {
    "plugs": "*",
    "slots": [
      {
        "wheels": ["UKW-B"]
      },
      {
        "rotating": true,
        "wheels": ["I"],
        "positions": "*"
      },
      {
        "rotating": true,
        "wheels": ["II"],
        "positions": "*"
      },
      {
        "rotating": true,
        "wheels": ["III"],
        "positions": "*"
      }
    ]
  },
  "passes": [
    {
      "type": "hill_climb",
      "measure": "ic",
      "backtrackingMinNumPlugs": 5
    }
  ]
}

Error:

$ ./build/bomm ./data/queries/seg-fault-query.json -t 1
[1]    42143 segmentation fault  ./build/bomm ./data/queries/_seg-fault-aro-discord-2024-10-22.json -t 1

The error probably occurs due to omitted parameters in the Hill climb pass that are legal following the JSON query schema.
