I'm also still getting the function declaration crashes. Here my test scene:
(same scene i posted as "loop bug" for beta 5)
#declare I = 0;
#while(I < 2)
#declare C = pigment { crackle }
#declare CF = function { pigment { C } }
#declare I = I + 1;
#end
It crashes both for MSVC and ICL compile (beta7).

It crashes only with the intel compile here.
The isowood problems i have seem to be the same type. Same applies for
the problem Jan Walzer mentioned (crackle3.pov)

After some investigation I think I found the problem. It had to do with an
sometimes invalid pointer. Depending on the compiler and architecture as
well as the context the pointer could still have valid content and thus
POV-Ray would not crash at all or only crash sometimes or always. I don't
want to say that it is fixed yet because it never crashed for me in the
first place...

Yes, you're right. I just tried it with MSVC again, and no crash. (I hadn't
found out yet yesterday that i can directly click the 2 .exes, so i was
renaming them all the time - probably I mixed them somehow)
