Type "show copying" to see the conditions.
There is absolutely no warranty for GDB. Type "show warranty" for details.
This GDB was configured as "i386-linux"...Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".
(gdb) run
Starting program: /home/gotom/debian/glibc/bugs/debian-glibc-14717/a.out
Detaching after fork from child process 32245.
Cannot load symbol 'hello': %
Program exited with code 01.
