  Thanks for your interesting suggestion!
  
  I am running Linux on a machine with 96MB physical memory and with a 256MB
  swap. So, there should be plenty of VM. I even tried the reboot in order
  to start with a fresh startup (with X and other stuff running there was
  50MB free phys. memory available) but still with a SegFault crash. 
  
Please run your program in a debugger and check where it crashes.

  Have anybody tried this test on a different machine? Does it run at all?

It works on a FreeBSD system with 256MB main memory and 4GB swap.

  Any estimates in MB how big is acctually 2**111111111?

It is 111111112 bits, or 3472223 32-but words, or about 33447778
decimal digits.  One needs just about 14MB to store it.
