[cfe-dev] [libclang] Is there any method like get_children (python cindex) available for libclang or alternative to print the tree structure by the traversal method?

Can you narrow down the failure to a specific line of python + line of
the input translation unit? I suspect it might be something to do with
accessing a property of an invalid type.

Have you considered writing your program in python? I found that using
the ipython shell (with its tab-completion) was really helpful for
exploring the libclang API.

(I apologise for not actually answering your question, but I don't know
enough about the libclang C interface.)
