Previously, when the rotate_relay_log() function was called, an unresolved concurrent access to a shared resource occurred. As a consequence, MySQL terminated unexpectedly with a segmentation fault. To fix this bug, a mutex lock on the resource is now used during the rotate_relay_log() call, and MySQL no longer crashes in this scenario.
Description of problem:
MySql is crashing in reload_acl_and_cache at the time of calling rotate_relay_log.
Version-Release number of selected component (if applicable):
