0xffffffff00000000ULL mask does not take into consideration signed 32 bit integers and as result 2147483648 will be stored as -2147483648. Another mask should be used to correct the issue: 0xffffffff80000000ULL. It processes correctly the case of integers that are greater than 2147483647.
There are several gdb tests below: (gdb) p ((unsigned long long)2147483648 & 0xffffffff80000000ULL) $1= 2147483648 (gdb) p ((unsigned long long)2147483647 & 0xffffffff80000000ULL) $2 = 0 (gdb) p ((unsigned long long)2147483646 & 0xffffffff80000000ULL) $3 = 0 (gdb) p ((unsigned long long)4147483646 & 0xffffffff80000000ULL) $4 = 2147483648
