Backport #4339: Segmentation fault during Marshal.load
http://redmine.ruby-lang.org/issues/show/4339

Author: Sean Bradly
Status: Open, Priority: Normal
Category: core

Conditions that seem to have to be satisfied:

1) A call to Marshal.load must be interrupted by a context switch.
2) Another thread calls GC.start manually.
3) The object being marshaled needs to have a lot of child objects to be =
reliable.

This appears to be a thread-safety issue affecting Ruby 1.8.x only. It tr=
iggers reliably for me on:

Ubuntu     -> ruby 1.8.7 (2010-06-23 patchlevel 299) [i686-linux]
Ubuntu-rvm -> ruby 1.8.7 (2010-12-23 patchlevel 330) [i686-linux]
MacRuby    -> ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.=
0]
Mac-rvm    -> ruby 1.8.7 (2010-08-16 patchlevel 302) [i686-darwin10.4.0]
