* time/asctime.c (asctime_internal): New function, derived from asctime_r. Takes additional parameter which is the buffer length. Use snprintf instead sprintf, if it overflows, fail. (asctime_r): Call asctime_internal with 26 as buffer length. (asctime): Call asctime_internal with length of internal buffer. * time/Makefile (tests): Add bug-asctime_r. * time/bug-asctime_r.c: New file.
