Rathaxes fails on Instrumented C code containing “if” statements about rathaxes HOT 3 CLOSED

In order to find the source of the issue, it is mandatory to look into the  
stack trace.

This error means that the node type on which the function should be  
specialized is empty (most probably an attempt on a field 'type' where there is 
none defined). By looking into the stack trace, we should be able to identify 
where the error is made and then fix it.

Here is the stack trace:

Fixed with the commit 3f0f76d46ed6.

This was actually a defect in the Instrospection pass
