There could be a signed overflow in the following code. The expression, (32-logmask) is comprised between 0 and 31 included. It may be equal to 31. In such a case the left shift will produce a signed integer overflow. According to the C99 Standard, this is an undefined behavior. A simple fix is to replace the signed int 1 with the unsigned int 1U. Signed-off-by:
