My guess is that the floats don't match exactly. Something like this:
glClearDepth(0.000001), glGetParameter(DEPTH_CLEAR) => 0.0
assert(0.000001 == 0.0); // fails!

Derp, now I remember why I thought this was so simple: ClearDepth should truncate to [0.0, 1.0], so clearly we shouldn't get 32.0 back if we query it.
