I also get it if I run mysql-test-run with: --skip-slave-binlog simplifies the debug printout on the slave...

Verified with 5.1-wl2325 bk tree. Slave mysqld is what crashes.

There is a bug in SUMA that crashes ndbd (and, seemingly, mysqld) when we're trying to unsubscribe from an already removed event. I have a patch that prevents the ndbd (and hence cluster) crash as well as mysqld from crashing. The bank test still doesn't seem to go too well, so there are probably other bugs (there are also still valgrind warnings). Since I am no expert on suma, i'm wanting to discuss the patch before checking anything in.

Tomas believe that ignoring the error is ignoring the symptom of a larger problem, and that if we do get this signal, it is because something is seriously wrong somewhere else (quite possibly corrupted in bad ways) and we really should not continue. Currently looking for the api source of the problem.

Can no longer repeat with latest BK plus bk commit - 5.1 tree (stewart:1.1984) WL#2325 which seemed to fix things up on ppc.

Pushed to 4.0.26, 5.0.11. Can only reproduce with cluster replication though (5.1).

Clarification: only the second patch was pushed. First one deemed inadequate.
