Similar percentage.

However, CPU only talking about 1,5% of the CPU time.. (so clearly better)

No exception in 4.4.7.2
strcmp
_RTDynamicCast
drawinglayer::primitive2d::arePrimitive2DReferencesEqual
drawinglayer::primitive2d::arePrimitive2DSequencesEqual
sdr::contact::ViewContact::getViewIndependentPrimitive2DSequence

CPU time in this area, 0,63%

No clue how I should rate this kind of 'issue'.  Except it appears to impact the performance in large > 600 pages bug docs (especially if you looking at a bug doc with a multitude of _CxxUnregisterExceptionObject errors in different area's). 

Not even sure who to ask, you Armin Le Grand or Tomaž Vajngerl  

And the other part is of course, does this require a bibisect c.q. would a bibisect be helpful. Or is this related to changes to the VCRUNTIME. LibreOffice 4.4.7.2 uses 110. LibreOffice 5.0.6.3 1.2?

I expect b236b36475ed9a204ac931c34ccc23205296a0a6 handled this.
