--- Comment #4 from Murugesan Nagarajan <murugesandins at gmail dot com> ---
Thank you for your comment.
I feel that there WAS a bug in old libc library.
I am not sure if current libc version having this bug or not.
-----------------------------------------
01. external library /lib64/libc.so.6 =3D> /lib64/libc-2.17.so
$ /usr/bin/g++ -g -Wall libcversion.cpp -o ./a.out
$  ./a.out
GNU libc version: 2.17
This should have been fixed in later versions of libc.
I need to know related libc version without this bug 109074.
-----------------------------------------
02. Bug related information from core file:
$ /usr/bin/g++ -DLINUX -g -Wall thread.cpp -o ./a.out -std=3Dc++11
