> The first problem is difference between implementations of the
> format_bad_address() in 0.printf.cpp file and _rw_fmtbadaddr() in rwtest
> library. The _rw_fmtbadaddr() uses _rw_fmtpointer() to format the pointer
> value (the pointer divided to parts with size = sizeof (long) and these parts
> are separated with colon ':') while format_bad_address() formats the pointer
> as integer by casting it to size_t. The same problem when "%p" and "%{f}"
> formats are tested: the expected value hardcoded in the test is a string with
> 16 numerals
> I'm not sure what should be corrected: the format_bad_address() and
> expected results for pointer formatting in 0.printf test of the
> _rw_fmtpointer() in test driver?
> The second problem is difference between implementations of the
> _rw_fmtlong() and _rw_fmtllong(). I think they should be implemented the same
> way.
