Description of problem:

compiling the espresso package, URL: http:/www.pwscf.org
(using g95 through gcc)

when trying to compile the constraints_module.F90 file  the following error appears:
cpp -P -traditional -D__LINUX -D__FFTW -D__USE_INTERNAL_FFTW -I../include 
constraints_module.f90 -o constraints_module.F90
gfortran -O -D__LINUX -D__FFTW -D__USE_INTERNAL_FFTW -I../include  -I.
-I../Modules -I../PW -I../PH -I../iotk/src -I../CPV -c constraints_module.F90 -o
constraints_module.o
constraints_module.F90: In function ‘set_structure_factor’:
constraints_module.F90:312: internal compiler error: in find_lattice_value, at
tree-complex.c:133
the same happens when using the precompiled g95 binaries from the g95 site.
