Most importantly, it makes use of 2 functions named "sel".  And it is
confusing them.  Hmm, further experiments show that the bug persists if
one of the sel()s is renamed.

I added
   fprintf(stdout,"sel1\n");
to the first sel, and
   fprintf(stdout,"sel2\n");
to the second sel.

Here is my output:

sel1
bob is odd
sel2
bob is NOT even

sel1
bob is odd
sel1
bob is even

Don't nest the functions and it just works.
