------- Comment #3 from P dot Schaffnit at access dot rwth-aachen dot de  2006-05-03 11:44 -------

Hi!

I believe this could be related: compiling the following with any optimisation
(starting from -O1) causes the following error:

initFeldVonDatei.f90: In function 'initfeldvondateiphase2korn':
initFeldVonDatei.f90:1: internal compiler error: in n_of_executions_at_most, at
tree-ssa-loop-niter.c:1772
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Shall I file a bug? Am I doing something wrong?

Thanks!

Philippe

PS: the build command I'm using:
gfortran -O1 -c Sources.f90

PPS: the source
      SUBROUTINE initFeldVonDateiPhase2Korn
!
      IMPLICIT   NONE
      INTEGER                ::   Grain_Number
      INTEGER, ALLOCATABLE    ::   New_number(:)
!
      Grain_Number = 0
      Reordering: DO
          IF ( ALL ( New_number .GT. 0 ) ) EXIT
          Grain_Number = Grain_Number + 1
          New_number(MINLOC(New_number)) = Grain_Number
      ENDDO Reordering
!
      RETURN
      END SUBROUTINE initFeldVonDateiPhase2Korn
