The following code returns a "Parse error : must have at least one entry in
map".
Declaring the layers separately doesn't cause the problem. (Beta 6, WinNT4)

light_source{<-1,1,-1>*5 rgb 1}
#declare txtSol=
    texture{
        pigment{rgb 1}
        normal{
            average
            normal_map{
                #declare i=1;
                #while (i<10)
                    [1 bumps .1 scale i]
                    #declare i=i+1;
                #end
            }
        }
    }

    texture{
        pigment{rgbt <1,0,0,1>}
        normal{
            average
            normal_map{
                #declare i=1;
                #while (i<10)
                    [1 bumps .1 scale i*2]
                    #declare i=i+1;
                #end
            }
        }
    }

Don't work in v3.1g either.

I can extend description of this bug.
it is not connected with parsing of normal_map but rather with parsing
of leyered texture. Why ? Becouse take second line

>                #declare i=1;

and move it line by line to top. It always shows parse error within
statememnt opened before this #declare

after 4 weeks I'm back to play with betas

I know, maybe this has been so since v3.1 and before.  Reason I think that
is because I had encountered the inability to use #declare, #while, #if,
etc. within a texture at certain times (layers).  You'll get a warning about
the parse seeing a "#" in a layered texture.

I brought it up before here at the newsgroups but I can't find the message
posts about it now.

I can extend description again. It's not connected with parsing of
leyered texture but parsing of declaration of leyered texture. When
the same specification of leyered texture is passed directly to the
plane everithing is ok.
