Major Description
When a non-Galera build is started with a dummy wsrep_provider:
# mysqld options required for replay: --wsrep_provider='dummy' |
SET GLOBAL wsrep_on=ON; |
It leads to:

The -2147284456 number is abritary, and it's value seems to depend on the string provided as wsrep_provider (here dummy), as well as the server version (it is not consitent between versions but it is consistent when the SQL is repeated): it looks like a bad memory read or similar.
An UB+ASAN build does not show any related output.
