[Mesa3d-dev] Normals initialization problem

[<jo...@du...>]

Hi all,

I have the following problem with Mesa3.3:
 -I use the application xlockmore, running as
   xlock -mode random -modelist cage -nice 0 -inwindow
  as test application.
 -On my VMS box it crashes in
    LIBMESAGL  SHADE  shade_fast_rgba_two_sided_compacted
                                        26882 0000000000010C00 0000000000AD56E0
    because of a floating overflow
  On my AIX box it runs correctly.
 -The given line 26882 is somewhat below line 155 in shade_tmp.h. If I check
  normal[0],normal[1] and normal[2] at line 155 I get
    on VMS:
       normal : 0.000000 0.000000 1.000000
       normal : 1103029150191208900000.000000
         1130982216341569100000000000000.000000 0.000000
      {CRASH!!!!}
	 
    on AIX
       normal : 0.000000 0.000000 1.000000
       normal : 0.000000 0.000000 0.000000
       normal : 0.000000 1.000000 0.000000
          etc....
 -Skipping the illogical normals in shade_tmp.h give as far as I can see the
  right result on the screen.
 -Looks like that the normals are not initialized to zero on VMS but where???
  Any ideas?
