CID 467268:    (INTEGER_OVERFLOW)
Expression "32UL + bitmap_size", which is equal to 31, where

"bitmap_size" is known to be equal to 18446744073709551615, overflows
the type that receives it, an unsigned integer 64 bits wide.
824 size_t size = sizeof(*res) + sizeof(*report) + bitmap_size;

It's correct, this could overflow, though as this is example code, it
doesn't matter. Nonetheless let's make this be a saturating add.
