Ah, yes, now I see. I had missed the assignment to 't' inside the asm
statement. I'll fix that.
The second test case seems borderline to me. I'm not a language lawyer,
but I don't know what are the rules wrt assigning using random integer
values to a pointer. We can mark the pointer with the 'may point to
global memory' attribute.
