[Pw_forum] error in ph( ir and raman spectrum)

[Carlos Reis]

Dear Users and Developers

I am obtaining a error in version 4.1.2 that I did not get with version 4.0.3

from phq_setup : error #         1
     third order derivatives not implemented with GGA

Any idea why this shows up in 4.1.2 and not on 4.0.3. Does 4.0.3 have a bug?

the input file is this one:

 &inputph
  outdir = '/dev/shm/clr/ti',
  tr2_ph=1.0d-14,
  alpha_mix=0.1,
  fildvscf='tidv',
  fildyn='ti.dyn',
  ldisp=.true.
  epsil=.true.
  lraman=.true.
  reduce_io = .true.
 nq1=1, nq2=1 nq3=1
 /

Best reagards,
