[Pw_forum] problem with bands.x

[Krishna chaitanya]

Dear Prof.  Paolo Giannozzi

My sincere apologies for the incomplete details about my issue. I am using
PWSCF version 5.0 compiled with intel fortran 12.1.6 version, gfortran
4.7.2 and mpich 3.0.2 environment.

When I am trying to do band structure calculation according to webpage  *
http://people.sissa.it/~degironc/QE-Tutorial/examples_pwscf_ex.tgz *I am
getting the following error for silicon case.

*Program received signal SIGSEGV: Segmentation fault - invalid memory
reference.*
*
*
*Backtrace for this error:*
*#0  0x2B8949244F27*
*#1  0x2B89492454F4*
*#2  0x3D036302CF*
*#3  0x2B894A53B270*
*#4  0x2B894825748C*
*#5  0x2B89473DC47D*
*#6  0x411782 in cgracsc_ at cgracsc.f90:67*
*#7  0x4084D8 in punch_band_ at bands.f90:331*
*#8  0x40951E in do_bands at bands.f90:112*
*
*
*[1]+  Segmentation fault      ../bin/bands.x < bands.in > bands.out*

Moreover nothing is written in bands.out and bands.dat files. I hope with
this information I will get solution for the above error.
