Its because in wsrep-patched server, tc_log is being initialized to tc_log_dummy
for wsrep builds.
...
tc_log= (total_ha_2pc > 1 ? (opt_bin_log ?
(TC_LOG *) &mysql_bin_log :
#ifdef WITH_WSREP
(WSREP_ON ?
(TC_LOG *) &tc_log_dummy :
(TC_LOG *) &tc_log_mmap)) :
#else
(TC_LOG *) &tc_log_mmap) :
#endif
(TC_LOG *) &tc_log_dummy);
...
Are there any interesting lines in the mysql error log? Would really like to see the entire error log if possible. Otherwise, can only speculate about the cause. My guess is that there are open transactions when tokudb's panic function is called.
