Quartus_cdb (17.1/18.0) crashes while generating VQM for StratixV for a simple adder

Hi All, 

 

I am using Quartus17.1 as well as Quartus 18.0 

 

quartus_cdb crashes with following error only when StratixV family is used: 

*** Fatal Error: Segment Violation at (nil) 

Module: quartus_cdb 

Stack Trace: 

0xbbd90: DEV_DEVICE::get_pad_info() const (ddb_dev)

); 

input [23:0] in2,

Please let me know any solution to this issue.
