----------------------------------------
Bug #17020: ObjectSpace.trace_object_allocations_stop raises if called before trace_object_allocations_start
https://bugs.ruby-lang.org/issues/17020#change-87123

* Author: byroot (Jean Boussier)
* Status: Closed
* Priority: Normal
* Assignee: byroot (Jean Boussier)
* ruby -v: ruby 2.5.8p224 (2020-03-31 revision 67882) [x86_64-darwin19]
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
The error is easy to reproduce:

e.g. on Ruby 2.3:

```
$ ruby -robjspace -e 'ObjectSpace.trace_object_allocations_stop'
-e:1:in `trace_object_allocations_stop': wrong argument type false (expected tracepoint) (TypeError)
	from -e:1:in `<main>'
```

Up to ruby 2.7.1:

```
$ ruby -robjspace -e 'ObjectSpace.trace_object_allocations_stop'
Traceback (most recent call last):
	1: from -e:1:in `<main>'
-e:1:in `trace_object_allocations_stop': wrong argument type false (expected tracepoint) (TypeError)
```
