Observed against up-to-date mysql-6.0-falcon-team branch at 2009-06-16, on both a 4-core Linux Red Hat host and an 8-core Solaris 10 x86_64 host.
This bug is tightly related to Bug#36631 (Assertion in SerialLogControl::nextRecord).
How to repeat:
Branch mysql-6.0-falcon-team or some other recent bzr branch containing Falcon code and tests.
cd mysql-test
perl mysql-test-run.pl --suite=falcon --big-test --suite-timeout=1440 --testcase-timeout=120 falcon_bug_22154-big
