It's in 6.0-codebase-bugfixing branch (http://pb2.norway.sun.com/web.py?template=show_pushes&branch=mysql-6.0-codebase-bugfixing) Builds: 'jorgen.loland@su... 2010-01-26 07:30:23', 'alik@sun.com-201... 2010-01-22 09:42:22' Just search for the test case name.

Analysis This crash happened only in 6.0-codebase (6.0) but never in mysql-next-mr (5.5, 5.6), and is believed to be related to the implementation of my_atomics that was different in 6.0-codebase for solaris at some point, due to merge issues. Given that the 6.0-codebase is abandoned, and that the same bug does not appear anywhere else, this can be closed.
