TMS320F280049C: complie optimizate defect

Hi teams,

complier version: 18.12.4

I complie my source code without enable complier optimization, it works well and without any complie error.

But once if the optimization enable with O2, the consoles shows 

>> Compilation failure
driver/e2prom/m24256/subdir_rules.mk:9: recipe for target 'driver/e2prom/m24256/m24256.obj' failed

>>>> Optimizer terminated abnormally
>>>> in function _m24256_get_state()
>>>> in file "../driver/e2prom/m24256/m24256.c"
This is caused by a defect in the TI C/C++ Optimizer.

In the function 

enum e2prom_state m24256_get_state(struct e2prom_drv *drv)
{
    return (container_of(drv, e2prom_type, drv))->state;
}

about the macro "container_of " 

#define offset_of(type, field)     ((unsigned long)&(((type*) 0)-> field))

#define container_of(ptr, type, member)   (type *)((long)ptr – offset_of(type, member))

by the way, the "container_of" macro also be used in other source files, but it still works and without any compile error

I cannot understand why the error only occurred in this function.

Please help me to solve this issue, thanks.
