fatal:MultiDValDelParent when returning logical attribute

Dear all,

I have found the most strange behaviour on a simple function returning a logical attribute (e.g. get_res_value).
For different combinations of the values of the logical variable and the (default) logical attribute
I get a fatal:MultiDValDelParent or even a Segmentation fault.

The attached script is an minimal example.
The example returns:
       True_at_False
       True_at_True
       True_at_False
fatal:MultiDValDelParent: Attempt to delete parent from empty list
       True_at_True
       False_at_False
       False_at_True
fatal:MultiDValDelParent: Attempt to delete parent from empty list
       False_at_False
       False_at_True
fatal:Variable res is still undefined, can not continue
Segmentation fault

I am at lost here. Does any one else get the same error messages?
Is if this a bug in NCL or there is something wrong with my local install?

Thanks in advance,
Álvaro.
