Sorry, thats new to me. It does not happen anywhere else with my own
templates. Also I'm not completely sure this is really harmless. My code
works with 1.32.0 (+ Solaris patches) and with 1.34.0 [assign] list_of
does not work any more. The two warnings are the only thing the compiler
complains about. My wild (stupid??) guess was, this is related.

I will debug the problem in detail and post my results.
