You sure? I was going by https://en.wikipedia.org/wiki/Ivy_Bridge_(microarchitecture)#Desktop_process...
There would be a significant change between Ivy Bridge and Haswell, since it's a "tock" type of Intel development where the micro-architecture changes. And that sort of change may affect the bug we're discussing. Particularly if someone put in a fix for Haswell CPUs and mis-applied it to IvyBridge too :-)
No, you and Wikipedia are right and I was wrong. Intel's ARK page says it's Ivy Bridge. I was under the impression that Intel numbering was consistent, i.e. i3/5/7-3xxx was Ivy Bridge and i3/5/7-4xxx was Haswell, but I was naive.
Thanks for making me double check.
I own an i5-3570K that calls itself Ivy Bridge and a couple of laptops with i5/7-4xxx which both call themselves Haswell. So I extrapolated. :)
