Sorry it took me a while. I kind of suspected that it is a gcc problem so
I decided to spend some time to recompile gcc 3.2.3 and see whether I see
a problem there. I did not. Here is the output from gdb
$gdb ./povray
{ here comes the usual header from povray, no problem there}
Statistics Stream to console....On
Warning Stream to console.......On

-- I am not terribly good at debugging. Does anyone have an idea what to try next?
(again I use gcc 3.2.3 on alphaev68 (this time, same problem with ev56) )
Thanks for any pointers ...
