Ah... Long ago in a universe far from here... I remember, I had the 
same problem on MacOS9 at some point.

But the strange thing with the current incarnation of the problem is 
that the exact same binary (build on OSX 10.2) passes test_coercion on 
10.2 but fails it on 10.3. Could the C library be involved?
