Could not reproduce on MySQL 5.5 or MySQL trunk.
Please note that the test case requires semisync plugins, so they should be built and placed in the plugin folder.
On the same reason the test case is not applicable to versions below 5.5.
The test case works pretty reliably for me, but a couple of times (out of dozens) it didn't cause the assertion, so I needed to re-run it.
