15:50.46 starseeker brlcad: sh_light.c:1682 is causing clang's static analyzer to bark about dereference of undefined pointer value
15:56.27 Stragus Just wondering, "sh light" as in spherical harmonic lights?

18:51.37 brlcad starseeker: sh_light is just a standard light ... sh is "shader"
18:52.01 brlcad lights are assigned by setting their shader to "light" as it's an optical property
18:58.33 brlcad that particular snippet is just trying to figure out each light's level
18:58.45 Notify 03BRL-CAD:brlcad * 70145 brlcad/trunk/src/liboptical/sh_light.c: op precedence
18:58.45 brlcad try that, looks like parens missing
21:15.53 Stragus Ah, right. Spherical harmonics seemed pretty modern stuff, for BRL-CAD
21:31.44 starseeker brlcad: nope, still unhappy - it may think there's a way for the pointer to remain uninitialized?
21:37.11 starseeker ok, here we go: loop condition false line 1647, false branch 1652, loop true 1666, false 1669, false 1673, false 1678, undefined dereference 1682
21:49.59 Notify 03BRL-CAD:starseeker * 70146 brlcad/trunk/src/libgcv/plugins/gdal/gdal.cpp: xy gridding wasn't right - this fits the outline better, but still not 100% sure its accurate...
