if you don't use the unlimited objects option, then the Classic API 
objects are statically allocated in RTEMS 6. You can construct tasks and 
message queues with user-provided storage:

https://docs.rtems.org/branches/master/c-user/task/directives.html#rtems-task-construct

https://docs.rtems.org/branches/master/c-user/message/directives.html#rtems-message-queue-construct

The POSIX and C++ synchronization objects use user-provided storage.

I would look at the linker map file. You probably use a file system.
