Optimizer
Server crash in JOIN_CACHE::free or in copy_fields ()
Queries that use DISTINCT and an always-constant function like COLLATION(aggegate_func(...)) could cause a server crash. Note that COLLATION() is a special function - its value is constant even if its argument is not costant.
Crash when using ANY predicand with redundant subquery in GROUP BY clause ()
MariaDB Server SEGV on INSERT .. SELECT ()
Certain queries in form "INSERT ... SELECT with_aggregate_or_window_func" could cause a crash.
Wrong result with table elimination combined with not_null_range_scan ()
If one runs with optimizer_switch='not_null_range_scan=on' (which is not enabled by default), a query that does a join and has const tables could produce a wrong result.

A query with a subuquery in this form could cause a crash:
Subquery semi-join optimization could miss LooseScan or FirstMatch strategies for certain queries.
Optimizer uses all partitions after upgrade to 10.3 ()
For multi-table UPDATE or DELETE queries, the optimizer failed to apply Partition Pruning optimization for the table that is updated or deleted from.
Range optimizer regression for key IN (const, ....) ()
The issue can be observed on and later versions which have the fix for . That fix introduceds optimizer_max_sel_arg_weight.
If one sets optimizer_max_sel_arg_weight to a very high value or zero (which means "unlimited") and runs queries that produce heavy-weight graphs, they can observe a performance slowdown, e.g.:
If one uses histogram_type=JSON_HB, has collected a histogram of that type and runs a query that selects a very narrow range near histogram end, they can hit an assertion in the optimizer due to rounding errors in the histogram causing negative selectivity.
