I have spent two days on this without any clue. Sigh :(

left shift error can be fixed with 1U << ((bit) & XBM) (change int 1 to unsigned int). devtools::check(check_dir = ".") works, but devtools::check() still fails. Why???

I finally find the bug. I used C's strcpy function in the code. The char array I defined is too short to store the temp filename which is longer than regular file.
