Michael MacDonald added a comment - 2013-10-15 21:05 - edited I realized that I attached the mysql-error.log from a 5.5.32 server, but it also still affects a 5.5.33a server. Here is the log from that server 131015 13:51:28 [ERROR] mysqld got signal 11 ; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. To report this bug, see http://kb.askmonty.org/en/reporting-bugs We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail. Server version: 5.5.33a-MariaDB-log key_buffer_size=134217728 read_buffer_size=131072 max_used_connections=12 max_threads=502 thread_count=1 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1232371 K bytes of memory Hope that's ok; if not, decrease some variables in the equation.

Oleksandr Byelkin added a comment - 2013-10-15 22:22 it is just wrong query which crashes before error is returned... So it should be fixed.

Oleksandr Byelkin added a comment - 2013-10-21 13:12 The problem is that mysql_derived_prepare do not check result of sl->handle_derived() call.
