Dear guru,  
This happens intermittently. Is this a bug?

Command: gr\_modtool makexml integer\_sink2  
Output: as below

Probably. That said, makexml is the most tricky part of modtool. This  
might be triggered by invalid code, although the error message suggests  
otherwise.

Can you please post GNU Radio version, the include file and the \_impl.cc  
file that triggers this.
