Brute force abort for a transaction which is in lock wait state for some other lock (than the conflicting lock with BF applier), causes assert in debug build. Probably a segfault would happen with optimized build.

Problem is in the way that the victim transaction grants conflicting lock for the BF thread.
Fix is pushed in revision: http://bazaar.launchpad.net/~codership/codership-mysql/5.6/revision/3910

DDL processing for a DDL statement, which fails, will cause a segfault. Test case here:

CREATE TABLE t(i int);
CREATE TABLE t(i int);
DROP TABLE t;

Segfault will happen during the DROP TABLE processing.
