The signature of FastPrimitiveArrayAllocatorFuncPtr is Object* FastPrimitiveArrayAllocatorFuncPtr(CorElementType type, DWORD cElements). It creates array of a given primitive type.

I think that the problem was introduced in dotnet/coreclr#12369. The following line should not have been removed: https://github.com/dotnet/coreclr/pull/12369/files#diff-a894b2fd6ca33d239bd799a1ccccb59cL942 . Instead, there needs to be an extra instruction added to convert the relative pointer to obsolute pointer.
