Actually, it appears that those are false-positive, that is, the use of the pointer only happens when a condition (mb_prebuilt is true) is set that doesn't happen until after the pointer is initialized. PVS just didn't get it correctly.
We should probably forward those to Tuxera anyway. And update NTFS-3g, our version is from 2014.
