Hi,

I am computing phonon band structure for BCC Pb.  kpt mesh is 16 16 16 
and qpt is 8 8 8.  If I merge the DDB files and
try to use "anaddb" for analysis it shows a seg. fault.  I am pasting 
the last few lines below:


================================================================================

Dielectric Tensor and Effective Charges

-begin at tcpu      0.168  and twall      0.169 sec
The Gamma block is :     30

Metallic case : effective charges are set to 0

================================================================================

Calculation of the interatomic forces

-begin at tcpu      0.168  and twall      0.169 sec
mkifc9 : enter chkrp9
mkifc9 : exit chkrp9
mkifc9 : enter smpbz
      Homogeneous q point set in the B.Z.
      Body-Centered Lattice Grid
forrtl: severe (174): SIGSEGV, segmentation fault occurred


Things worked great when I used a 12 12 12 k-mesh and a 6 6 6 q-mesh.  
Could this seg. fault be related to array sizes?

Thanks,
Ganesh
