RE: [cdt-dev] -var-create on typedef'ed array inside a structure fails

Hi,

I was able to reproduce the problem with GDB 6.8, and CDT 5.
  
127-var-create - * *(((student).array_variable)+0)@5

It is the +0 that causes the problem.
It seems GDB does not like to do pointer arithmetic on
student.array_variable
because it is of type 'k'.  If it was of type long[5], it would work.
This sounds like a special case to handle.

BTW, you can try it with DSF instead of CDI, this example did work with
DSF.
