What should we do for a test case here? I feel that it should have one,
but the minimal testcase is *inherently* 239K, so I'm not quite sure
what to do here.
I guess ideally the testcase would generate a giant case statement, try
to compile it, and kill the process if it took longer than (x) seconds.
This is completely out of the normal test scheme however.
