### Object marshal max stackdepth support
|
||||||
|
|
||||||
|
Contexts can specify a stack depth limit for object marshalling. Max depth is unbounded by default.
|
||||||
|
|
||||||
|
```ruby
|
||||||
|
# terminates script if stack depth exceeds max during marshal
|
||||||
|
context = MiniRacer::Context.new(marshal_stack_depth: 500)
|
||||||
|
context.attach("a", proc{|a| a})
|
||||||
|
|
||||||
|
context.eval("let arr = []; arr.push(arr); a(arr)")
|
||||||
|
# => RuntimeError is raised
|
||||||
|
```
