Our autotesters have a jump of this magnitude between
K8: good r171332, bad r171367
K10: good r171399, bad r171360
IA64: good r182218, bad r182265
needs further bisection, there are a few candidates within the 171399:171360
range. IA64 is supposedly sth else (the fix for PR21617 pops up here).
Confirmed at least.
