Bug #10686: Memory leaking from torture test of symbol GC
https://bugs.ruby-lang.org/issues/10686#change-50738

* Author: Charles Nutter
* Status: Open
* Priority: Normal
* Assignee: 
* Category: core
* Target version: current: 2.2.0
* ruby -v: 2.2p0
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
The following code appears to grow without bounds when running on MRI 2.2p0 (and grows *very* fast...hold on to your RAM):

```ruby
x = 0; loop { (x += 1).to_s.to_sym }
```

I asked ko1 about this on Twitter and he said it appears to be leaking strings somewhere.
