root4star/St_geant_Maker deadlocks on SIGSEGV in malloc

[veprbl]

A workaround for this is

St_geant_Maker *geantMaker = dynamic_cast<St_geant_Maker*>(chain3->GetMakerInheritsFrom("St_geant_Maker"));
geantMaker->Do("/KUIP/SET_SHOW/BREAK OFF");

Naturally, I still see the crashes with this, as the underlying problem is not resolved.
But I also see some occasional deadlocks like this

And I don't understand how this one can happen.
