Calling delete on void* has undefined behavior, and may corrupt your
    heap. Do not do it.

Well, I am not running linux, but on freebsd5 using gcc 3.3 it prints:

    Main Thread
    Main Thread
    Main Thread
    Main Thread
    Main Thread
    Main Thread
    Main Thread
    Main Thread
    Main Thread
    Main Thread

So please post the output of gcc -v, your glibc version, and the
    output of uname -a . I suspect your gcc is misconfigured somehow.
