I hate enum in struct ............ it wasted me a whole week.
I am sure a patch must be submitted to the kernel to prevent others
from experiencing my pain.
If you think you meet my problem, the best way to test is to compile all
your
source codes in the same compiler, and the same optimizing options, which
will not cause this problem
