    Memory pool initialization is not guarded.
    

Problem conclusion

  • In version 8.0.1, changes were made to the framework in
    order to solve this problem. Now you can define
    OM_USE_STATIC_MEMORY_POOL_INITIALIZATION macro in
    omosconfig.h and recompile the framework. This will result
    in initialization of static memory pool in the pre-main
    phase of runtime execution. Note that this flag cannot be
    used if the user defines their own memory manager.
