Dear,
Dear QE professionals,
I am running a scf  calcuation for triclinic strcture but while reading
input file it shows
"Bad data for namelist object celldm
Bad data for namelist object celldm"

But program running without any error and giving output without considering
the celldm(4) and celldm(5) from the input file.

Here with i am pasting the output portion  of reading the name list  and
input file.

     Program PWSCF v.4.3        starts on  4Sep2011 at 14:17:47

     This program is part of the open-source Quantum ESPRESSO suite
     for quantum simulation of materials; please cite
         "P. Giannozzi et al., J. Phys.:Condens. Matter 21 395502 (2009);

     Parallel version (MPI), running on     4 processors
     R & G space division:  proc/pool =    4

     Current dimensions of program PWSCF are:
     Max number of different atomic species (ntypx) = 10
     Max number of k-points (npk) =  40000
     Max angular momentum in pseudopotentials (lmaxx) =  3
     Waiting for input...

     Subspace diagonalization in iterative solution of the eigenvalue
problem:
     a serial algorithm will be used
