Bug #10868: Object allocation within an extension during garbage collection terminates the Ruby process
https://bugs.ruby-lang.org/issues/10868#change-51550

* Author: Charles Leu
* Status: Third Party's Issue
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-linux], ruby 2.1.5p273 (2014-11-13 revision 48405) [x86_64-linux], ruby 1.9.3p551 (2014-11-13 revision 48407) [x86_64-linux]
* Backport: 
----------------------------------------
It appears that when a CFUNC makes an allocation when garbage collection is running within a different thread/context, it yields the error "[BUG] object allocation during garbage collection phase" and the Ruby process is subsequently terminated.

Ruby versions 1.9.3, 2.1.5, and 2.2.0 all yield the same behavior (per the attached files).

Note that similar behavior has been reported within issues 7750, 9090, and 1049.
