New issue 1646 by [email protected]: Segmentation fault in
v8::internal::Logger::is_logging
http://code.google.com/p/v8/issues/detail?id=1646
While working on an internal project based on PyV8
(http://code.google.com/p/pyv8/) I identified what seems to be a bug in V8.
buffer@alnitak ~/pyv8 $ python PyV8.py
