Which version of gfortran are you using (cf. "gfortran -v")? The bug looks similar to PR 18783 or PR 15181, which were fixed in 4.0.0 (before 2004-11-29 - 7 years and 7 releases ago). In case you have GCC/gfortran 4.0: I strongly urge you to upgrade. 4.0 was the first GCC version with gfortran and it was rather buggy. You should at least use GCC/gfortran 4.1.2 but better 4.3 or newer. Recommended released versions are 4.5 or 4.6 - or the developer version 4.7, which is typically also quite stable. An overview about the latest releases and the currently maintained version is given at http://gcc.gnu.org/ (right column) There could (should?) be newer GCCs available from your Linux distribution (assuming you are using Linux), but you could also try the build listed at http://gcc.gnu.org/wiki/GFortranBinaries If the internal compiler error still occurs with a newer GCC version, we can still start the tedious debugging work.
