Hi,

I tried executing the attached program in my system cygwin(win32/g++ (GCC) 4.5.3/boost 1.51.0) with the input as 1000 but the program did not give any segmentation fault.

Hi,

I have tried this program on my Linux *64* bit platform (-m64) using gcc 4.1.2 and gcc 4.6.2 and it fails for me with both compilers. It does *not* fail when I compile on a 32 bit platform or with -m32. Hope this helps.

Thanks, Soren Soe
