Ok.

I just figured out how it works (I hope). I think I will try to write
some lines of text which may be added to the source as reference for
using AST_{RW}LIST.

My problem was that I had to create a dynamic AST_RWLIST and I had not
understand to create a struct for the entries. I thaught that I could
put ast_frames directly into the AST_RWLIST...
