The xlf compiler has more rigorous error checking than the Intel compilers.
The initial problem was the call arguments to evb_io_debug. It looks like
you either updated evb_io_debug at some point and forgot to update all the
calls or you meant to call evb_io_debug2 routine instead. I have tweaked the
CVS tree to address this - take a look and see if you think it is okay.

The failure beyond this fix looks like some weird compiler bug - I want to
see if I can reproduce it and then I'll check with IBM to see what it might
be. I wouldn't worry about your style for the moment since style shouldn't
crash a compiler.

All the best
