Subject: [ruby-core:72381] [Ruby trunk - Bug #11845] [Open] source_location against symbol.to_proc causes infinite loop

Issue #11845 has been reported by Kouhei Sutou.

----------------------------------------
Bug #11845: source_location against symbol.to_proc causes infinite loop
https://bugs.ruby-lang.org/issues/11845

* Author: Kouhei Sutou
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.3.0dev (2015-12-19 trunk 53202) [x86_64-linux]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
`ruby -v -e ':class.to_proc.source_location'` causes inifinite loop:

```text
% /tmp/local/bin/ruby -v -e ':class.to_proc.source_location'
ruby 2.3.0dev (2015-12-19 trunk 53202) [x86_64-linux]
(never finished)
```

It's also caused with ruby 2.3.0preview2:

```text
/tmp/local/bin/ruby -v -e ':class.to_proc.source_location'
ruby 2.3.0preview2 (2015-12-11 trunk 53028) [x86_64-linux]
(never finished)
```

This may be related to `Proc#call` optimization.
