Fixed In Version: Doc Type: Bug Fix
Doc Text:
Under some circumstances on the PowerPC 64 architecture, Ruby did not save the context correctly before switching threads. Consequently, when a thread was restored, it had stale context whose use would result in a segmentation fault. This affected nearly any thread-using program on PowerPC 64. With this update, the underlying source code has been modified to address this issue, and the context is now saved correctly.
