Analysis: At check_trx_exists function InnoDB allocates a new trx if no trx is found from thd but this newly allocated trx is not registered to thd. This is unsafe, because nothing prevents InnoDB plugin from being uninstalled while there's active transaction. This can cause crashes, hang and any other odd behavior. It may also corrupt stack, as functions pointers are not available after dlclose. Fix: The fix is to use thd_set_ha_data() when manipulating per-connection handler data. It does appropriate plugin locking.
