    runtime: fix 1-byte return during x.(T) for 0-byte T · d646040f
    Russ Cox authored
    The 1-byte write was silently clearing a byte on the stack.
    If there was another function call with more arguments
    in the same stack frame, no harm done.
    Otherwise, if the variable at that location was already zero,
    no harm done.
    Otherwise, problems.
    
    Fixes #8139.
