The fields in the TaskState heap_base, heap_limit and stack_base are all guest addresses (representing the locations of the heap and stack for the guest binary), so they should be abi_ulong rather than uint32_t. (This only in practice affects ARM AArch64 since all the other semihosting implementations are 32-bit.)
