"long" would not in general be the right type to use in cases where
 we do need to make this change, because "long" also can
be only 32 bits wide on some hosts.

[PATCH 0/2] avoid integer overflow

2020-03-16 Thread Yifei Jiang

it may exceed 32 bits, resulting in integer overflowing. So constant type need
change to "long"
