The other way around, otherwise right. XPV: alignof: 8 sizeof: 16 xpv_allocated: alignof: 4 sizeof: 8 XPVIV: alignof: 8 sizeof: 24 xpviv_allocated: alignof: 4 sizeof: 12 > If so, that would explain a lot, and it's my fault. Looking forward to the explanation :) Thanks for your work, -- Niko Tyni ntyni@debian.orgThread Previous | Thread Next
