I wonder why warning with "Camera is inside a non-hollow object...." is
outputed during rendering and not before. When I start rendering with
+GAfile.txt option, it contains at begining:
Creating bounding slabs.
Scene contains 3 frame level objects; 0 infinite.
Creating light buffers
Displaying...
Rendering...
-:--:-- Rendering line 0 of 3600 supersampled 0 times.
-:--:-- Rendering line 1 of 3600Warning: Camera is inside a non-hollow
object. Fog and participating media
may not work as expected.
supersampled 1927 times.
0:00:03 Rendering line 2 of 3600 supersampled 1872 times.

How do you test if it's inside?
You have to trace a ray, that's why it shows up on the first line.
I'm not that familiar with the code, so if it's wrong don't flame me.

Maybe it's done this way, but I'm sure it isn't necessary. You can test if
a point is inside an object by using (e.g.) inside(O,V). If you imagine the
whole scene as an union, you can test this way whether the camera is inside
any object.

No, you don't.
