TC_LOG_MMAP::log_one_transaction(my_xid): Assertion `p->ptr<p->end' failed

I have a simple test case that replaces a row in innodb and tokudb and
then commits. Eventually, mysqld hits this assert:

mysqld: /home/prohaska/maria10-build/mariadb-10.0.0/sql/log.cc:7547:
int TC_LOG_MMAP::log_one_transaction(my_xid): Assertion `p->ptr <
p->end' failed.

The test works great when the binlog is enabled. The test crashes
when the binlog is OFF. So, maybe the problem is isolated to the
TC_LOG_MMAP logic. I noticed that the TC_LOG_MMAP::unlog function is
quite different than the mariadb-5.5 version.

What is the best way to get this fixed? Would it help if i made the
test case available?

Thanks
