Coverity complained about implicit sign-extension in the BloomPageGetFreeSpace macro, probably because sizeOfBloomTuple isn't wide enough for size calculations. No overflow is really possible as long as maxoff and sizeOfBloomTuple are small enough to represent a realistic situation, but it seems like a good idea to declare sizeOfBloomTuple as Size not int32. Add missing check on BloomPageAddItem() result, again from Coverity. Avoid core dump due to not allocating so->sign array when scan->numberOfKeys is zero. Also thanks to Coverity. Use FLEXIBLE_ARRAY_MEMBER rather than declaring an array as size 1 when it isn't necessarily. Very minor beautification of related code. Unfortunately, none of the Coverity-detected mistakes look like they could account for the remaining buildfarm unhappiness with this module. It's barely possible that the FLEXIBLE_ARRAY_MEMBER mistake does account for that, if it's enabling bogus compiler optimizations; but I'm not terribly optimistic. We probably still have bugs to find here.
