[Pw_forum] (solved) Error in phonon calculation and during tests also?

[sonu kumar]

 Respected Prof. Paolo Giannozzi, Lorenzo Paulatto, Ali Tavana and all QE
users,

Thank you very much for your help.

Problem is solved with gfortran compiler ( gcc version 4.4.1 ).
All the tests and phonon calculations are working fine.

I used latest non-commercial version of intel fortran compiler.
Will try to check with other intel compilers.

will try with -O1 flag.
