The array is allocated with space for elements up to LAST_VALUE_TYPE and iPTR is defined after it. The enumerator value of iPTR is between LAST_VALUE_TYPE and LastSimpleValueType. For this reason the check VT.isExtended() fails and the value is looked up in VTs triggering an out of bounds access. In the version of LLVM we're using getValueTypeList even tries t...
