If we're constructing the string, assign the pointer to it to a non-const pointer variable, set the stat_tap_ui cli_string member to that variable, and then use the variable to free it when we're done. Don't cast away constness if we don't have to. Change-Id: If3b24dbf1c910e1e6eceb76f2f6a7ae3898315f9 Reviewed-on: https://code.wireshark.org/review/25952 Reviewed-by: Guy Harris <guy@alum.mit.edu>
