Description
When I compile the server with GCC 13.1.0, tests fail massively due to UBSAN errors on static initialization like the following:
static Sys_var_mybool Sys_automatic_sp_privileges( |
"automatic_sp_privileges", |
"Creating and dropping stored procedures alters ACLs", |
GLOBAL_VAR(sp_automatic_privileges),
|
CMD_LINE(OPT_ARG), DEFAULT(TRUE));
|
If I compile with GCC 12.3.0, no error is reported.
The minimal steps to reproduce this should be as follows:
cmake -DWITH_UBSAN=ON -DMYSQL_MAINTAINER_MODE=WARN /mariadb/10.5
|
cmake --build .
|
sql/mariadbd --no-defaults --wrong-option
|
The output that I am seeing is as follows:

It could be worthwhile to test this on clang as well, once MDEV-26272 has been fixed.
