I think I might have found a bug in the exection engine's 'constants
folding'.
Basically APInt's parameters are the wrong way round.
Line 577 for lib/ExecutionEngine/ExecutionEngine.cpp :-
case Instruction::PtrToInt: {
GenericValue GV = getConstantValue(Op0);
uint32_t PtrWidth = TD->getPointerSizeInBits();
GV.IntVal = APInt(PtrWidth, uintptr_t(GV.PointerVal));
return GV;
}
