Does this refer to the call to memcpy() in usb_hcd_poll_rh_status()?

Line 75 in string_32.h is part of the __constant_memcpy() function.  
That function should not be involved here because the length argument 
isn't a compile-time constant.

This has to be either a compiler bug or else a bug in the
implementation of memcpy.
