The problem is that the actual code is a member function of a class template another member function of which contains a hotspot, i.e. -O3 is important here. And because of the use of template, I can't easily compile one bit with -O2 and another one with -O3.
Basically, my hope was that I could tweak the code so as to spoil the optimisation that crashes. But for that I would need to understand the optimisation...
