I could reduce my test case a lot now to show where the gdb seg fault 
comes from. I believe that this might be also the solution to the actual 
problem, though I am not sure yet.

This produces a seg fault in gdb when setting a breakpoint to 
chartestmod.f90:5 and trying to print startdate:


chartest.f90:
-----------------------------
program char_test

use chartestmod

implicit none

    INTEGER Request_Type
    CHARACTER (LEN = 19) :: StartDate

    StartDate='2003-03-15 00:00:00'

    CALL GeomSim(StartDate)

end
-----------------------------

chartestmod.f90:
-----------------------------
module chartestmod

contains

SUBROUTINE GeomSim(StartDate)

    CHARACTER (LEN=*), INTENT(IN) :: StartDate

     print*, startdate

end subroutine


end module
-----------------------------



Now, change in chartestmod.f90 'LEN=*' to 'LEN=19' and gdb does not 
segfault anymore. I somehow think that this is related to my actual 
problem, so: any ideas if this is related to a gfortran bug?
