Looks like I previously logged MDEV-23092 for the last bug above ^ without updating filters. It can likely be marked as duplicate of this one, assuming the issues are the same.
This crash affects testing significantly as no core dump is written (resulting in re-reducing test cases each run)
More bugs in this area. This testcase (without [pre-]loading plugin):
SET NAMES utf8, collation_connection='utf16le_bin';
|
SET GLOBAL wsrep_provider='/invalid/libgalera_smm.so';
|
SET GLOBAL wsrep_cluster_address='OFF';
|
SET GLOBAL wsrep_slave_threads=10;
|
Results in no core dump, and the error log (optimized) shows:
