            Bug ID: 16429
           Summary: strptime truncate 64bit pointer to 32bit
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org

under 64-bit enviroment, when input an 64-bit pointer as arg1 to strptime, e.g,
a char[] array, it will return a pointer with higher 4 bytes set to zero. 
for example:

char timestr[655] = "2011-11-27T23:06:23qi/ning";
struct tm t;
char * ret = strptime(timestr, "%FT%H:%M:%S", &t);
printf("%llx %llx\n", ret, timestr);
printf("%c\n", *ret);
