readImageFromFileHeapSize -> initializeInterpreter -> initOpcode(index=1) -> error(s="opcode address is not an integer object") ->

This looks like you're not returning an Integer object (i.e. the lowest bit set) as the opcode address. This is required by Jitter to treat addresses as Integer objects.

printCallStack -> SIGSEGV :-(

The SIGSEV comes probably because the interpreter hasn't been initialized at all (you're still during the load phase of the image so that offsets may not have been adjusted yet).
