Please submit a full bug report,

See <URL:http://gcc.gnu.org/bugs.html> for instructions.

This problem must have been introduced in the last few days.
Sorry for the long testcase, I can try to reduce further in a few days.

With GNU Fortran 95 (GCC) 4.2.0 20051221 it works (I get a lot of 'undefined
reference' messages, but no ICE:s).  But with 20051222 I get the same ICE
message that Martin gets.  So it seems the problem was introduced within the
last 24 hours.  Confiremd.

To be a bit more precise: works with revision 108902, ICE:s with revision
108943.

Here's a reduced testcase:

----
module ModelParams
        implicit none

        type ReionizationParams
             real   :: fraction
        end type ReionizationParams

        type CAMBparams
             type(ReionizationParams) :: Reion
         end type CAMBparams

        type(CAMBparams) CP
end module ModelParams


module ThermoData
    use ModelParams
    implicit none

contains

    subroutine inithermo()
        use ModelParams
        if (0 < CP%Reion%fraction) then
        end if
    end subroutine inithermo

    subroutine SetTimeSteps
        if (0 < CP%Reion%fraction) then
        end if
    end subroutine SetTimeSteps

end module ThermoData

------- Comment #5 from pault at gcc dot gnu dot org  2005-12-27 05:53 -------
There are three different, temporary work-arounds:

(i) Remove all "use ModelParams" from the contained procedures;
(ii) Add a "use ModelParams" to subroutine SetTimeSteps; or
(iii) Change the order of the contained procedures.

In the meantime, I will sort out a solution.

I have just submitted a patch for this, which I intend to commit tomorrow
morning.

Thank you for reporting the bug I hope that the inconvenience is outweighed by
gfortran handling derived types correctly.

Great, thanks!

Absolutely! I'm not using gfortran for production at the moment, but run
regular tests with our local codes. I'm really looking forward to having a
free, standard-conforming, multi-platform and OpenMP-aware F95 compiler soon,
and gfortran is evolving very nicely :)

In your mail to gfortran you mentioned that you wanted to apply the fix to the
4.1-branch as well. Since the problem is not triggered there (I don't know
why), your patch is technically not a regression fix, so it might not be
appropriate there. Just a thought.
