--- Comment #7 from Dominique Pelletier <dominique.pelletier at polymtl dot ca> 2012-01-22 19:36:44 UTC ---
here is the full code

i compileeach file separately  with

gfortran -c

in the following order

problems_parameter_module.f03
air_module.f03
clound_module.f03
ground_module.f03
integrable_model_module.f03

the error message is

In function 'intgrate':
internal compiler error: in conv_function_val.
at fortran/trans-expr.c:2191
plese submitt a full bug report ....

I use gfortran 4.7.1 build 2012.01.19 on a windowx xp laptop with MinGW

Thnks
