Tom reported this to me too, sorry :-(
Do you have an idea how to fix this too? I am now installing arm64 toolchain.
I haven't looked at it yet. I've seen similar problems in the bast handled by casting between integer types before casting to pointers e.g. something like the following guess:
uint32_t pa; void *p = (void *)(uintptr_t)pa;
I just tried this, it should do the trick. Can you give it a spin ?

I am a bit worried about the u32 values all around the place. If the buffer would be above 4GiB, we might have a problem.
Do you know about some nice arm64 board with USB for testing?
There's always the Jetson TX1; it is the p2371-2180 that I was building above:
If you have one you don't need ... ;-)
