Takashi Yano 3d94e07c49 newlib: libc: Fix crash on fprintf to a wide-oriented stream. Previously, fprintf() on a wide-oriented stream crashes or outputs garbage. This is because a narrow char string which can be odd bytes in length is cast into a wide char string which should be even bytes in length in __sprint_r/__sfputs_r based on the __SWID flag. As a result, if the length is odd bytes, the reading buffer runs over the buffer length, which causes a crash. If the length is even bytes, garbage is printed. With this patch, any output to the stream which is set to different orientation fails with error just like glibc. Note that it behaves differently from other libc implementations such as BSD, musl and Solaris.
