The stressVector test fails on ix86 due to too strict check:

DeltaR   TLorentzVector      	 time = 0.2610929	(sec)
DeltaR   XYZTVector          	 time = 0.22973299	(sec)
DeltaR   PtEtaPhiEVector     	 time = 0.0016570091	(sec)
-12823.3585955796	-12823.35859557827	-12823.35859557827
Test DeltaR failed !!

The new value for the scale parameter (50) was calculated from the
above values:

root [2] (-12823.3585955796 - (-12823.35859557827)) / -12823.3585955796 / std::numeric_limits<double>::epsilon() / 10
(double) 46.762663
