Maybe. Of course I can't force you not to mix the unrelated changes.
I just hope that doesn't happen again.
Let's go to non-waste part.

It was I who found the cause of this problem.

And for the W32 port, it is true that the only purpose of the copying
is to avoid writing to the pure storage. But notice that some part of
the x_get_arg code I showed in the previous mail was enclosed with
"#ifndef WINDOWSNT", and the copying code in xfns.c and macfns.c had
existed before some frame parameter got allocated in the pure storage.
So, the primary purpose of copying is different between W32 and
X11/Mac.
