Dietmar, link you sent is about really really different problem (basically, it's not bug, but RFE for corosync).
Memory corruption in normal case cannot cause bug you have (of course, if you are not changing corosync process memory ;), what you are probably not doing). Best application for such test is testcpg.c. If there is really bug, can you please create BZ (ideally with way to reproduce, because I'm really not able to reproduce such behavior).
