Hello, When looking at the smatch database, I see the following: kernel/sys.c|prctl_set_mm|find_vma|556035|0|8017|1|$|0-s32max[c] kernel/sys.c|prctl_set_mm|find_vma|556035|0|1001|1|$|0-18446744073709551614 and: mm/mmap.c|__do_munmap|find_vma|607602|0|8017|1|$|1-u32max[c] mm/mmap.c|__do_munmap|find_vma|607602|0|1001|1|$|1-u64max I didn't expect the value ranges for the same callsite to be different, is this a bug - or is there something I'm not understanding? Thanks, Andrew Murray
