The bug is present in qemu.git, my patches don't touch it:

void isa_register_portio_list(ISADevice *dev, uint16_t start,
                              const MemoryRegionPortio *pio_start,
                              void *opaque, const char *name)
{
    PortioList *piolist = g_new(PortioList, 1);

^ leaked


    /* START is how we should treat DEV, regardless of the actual
       contents of the portio array.  This is how the old code
       actually handled e.g. the FDC device.  */
    isa_init_ioport(dev, start);

    portio_list_init(piolist, pio_start, opaque, name);
    portio_list_add(piolist, isabus->address_space_io, start);
}

It's only a problem if we allow unplug, which we shouldn't for these
devices.
