For the parent variable of the missing VOP SFT.6 there is no SFT with offset
zero in pD.1574_36 NMTs aliases. So the following triggers:

The bug goes like the following. We partition some of struct PgHdr fields
into MPT.47, stopping to do partitioning before we reach SFT.6 (which also is
a field of struct PgHdr) here:

Adding Diego, as disabling memory paritioning (--param max-aliased-vops=1)
results in correct alias info. Which hints at that the identified patch only
exposed the regression.
