example of problem

Tested on:
  gcc 3.4.1 on Mac OS X and
  gcc 3.2.3 on RedHat Enterprice Linux 3 AS (update 1)

The makefile builds 'test-bigger', 'test', and cleanShm.

cleanShm deletes the shared memory segment created by the other programs.

'test' and 'test-bigger' are created from the same source files.
The only different between 'test-bigger' and 'test' is that 'test-bigger'
declares a static array of integers before any includes in order to force
basic_string's _S_empty_rep_storage to move to a different location.

Execute 'test-bigger' before 'test' to observe the problem.
