Description Kris 2011-04-03 19:30:11 UTC 
Created attachment 23864 [details]
reduced program fortran code that triggers the internal error

I have reduced a fortran program to the attached test case that triggers the following internal error:

$ gfortran mio_component_ref_error.f90
mio_component_ref_error.f90:45.41:

    use elliptical_elements, only : line 
                                         1
Internal Error at (1):
mio_component_ref(): Component not found

This happens using gfortran 4.5.1, 4.6.0, and the trunk build from yesterday (4.7).  

The error goes away if you copy the line() function from the elliptical_elements module into the the solution_mod module and comment out the use statement on line 45.

Maybe this bug is related to bug 47601?  I am experiencing this problem in 64-bit Ubuntu Linux.

I don't know if the following tidbit helps, but while I was cutting the program down to this test case, I briefly experienced the following different error at the same location when I eliminated some of the extends() dependencies of one type on another in the type_definitions module.  I can't seem to reproduce this different error anymore, though.

gfortran -c  -o solution.o solution.f90
solution.f90:10.41:

    use elliptical_elements, only : line 
                                         1
Internal Error at (1):
free_pi_tree(): Unresolved fixup

This pr looks like a duplicate of pr47601.

This is PR47546, which was closed after the error reported vanished.
Can you reopen it and provide a case triggering it if you can reproduce again?

Indeed, and the testcase matches the same pattern (use-associated extended derived-type component needed in function interface).
