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
Reporter: hxnhxn at gmail dot com
CC: drepper.fsp at gmail dot com
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);

You may also want to file a bug report with GCC requesting that this be made default, since use of implicit function declarations is always an error and is a constraint violation. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
