Our GDB on AIX is a bit unstable and it doesn't seem to like the new page allocator for an unknown reason. Even an helloworld can't be run properly. It might be related to #35451 but I think it's more a GDB problem. The team working on it has been contacted. So until now, I would like to disable these tests in order to release our builder.
