Description
SET GLOBAL innodb_buffer_pool_size=12*1024*1024; |
Has very different outcomes depending on what version you use (note 10.4, and 10.8 vs other versions):

Given MDEV-28804, I am not sure if 10.3 to 10.7 are affected versions, or 10.4, or rather 10.8 to 10.10 etc. (i.e. these latter versions are not failing here, but look to be giving performance issues). In any case, 10.4 is failing.
