A smaller version of the previous file that isolates the problem.


I have now tried this test with gcc 3.3.3 (on a64) and the file still hangs.

Now that the example has been isolated, it appears that gcc's compile time is
exponential in the number of assignments in the included program.

See the comments in the attached source file for more details.
