| |
I have a program:
#include <stdio.h> #include <sys/types.h> #include <dirent.h>
int main() { DIR *dir = opendir("/uss/zzq/TIDs"); printf("dir = %08lx\n",(int)dir); }
which fails to work correctly under the development version of libc.
brian@remo brian>gcc foo.c (redhat 6.2 libc) brian@remo brian>./a.out dir = 08049760
brian@remo brian>xgcc foo.c (recent cvs libc) brian@remo brian>./a.out dir = 00000000
the machines remo runs 2.2.18pre15aa1 and the filesystem is reiserfs 3.5.26. The same thing happens if the filesystem is ext2.
gcc and xgcc invoke the same compiler: egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)
And here is the actual failure in the bowels of libc:
(gdb) s __libc_fcntl (fd=6, cmd=2) at ../sysdeps/unix/sysv/linux/i386/fcntl.c:44 44 arg = va_arg (ap, void *); (gdb) n 51 if (! __have_no_fcntl64) (gdb) n 53 int result = INLINE_SYSCALL (fcntl64, 3, fd, cmd, arg); (gdb) n 54 if (result >= 0 || errno != ENOSYS) (gdb) print result $9 = -1
What has gone wrong?
