I would consider backporting https://core.tcl-lang.org/tk/info/0d9c0d50f9 (tcltk/tk@ca38684090) instead to fix many additional instances of this issue.

I changed my mind about backporting the entire upstream change; it shows only two more instances where length was changed from size_t to int, so I have incorporated those as well as removed redundant (int *) &length casts.
