I downloaded the December 6 version of gfortran from http://quatramaran.ens.fr/~coudert/gfortran/gfortran-linux.tar.gz and attempted to compile the following file:
SUBROUTINE f1 INCLUDE "anything" END SUBROUTINE f1 SUBROUTINE f2 INCLUDE "anything" END SUBROUTINE f2 The INCLUDE file can contain anything. I got the following message: f.f90:1: internal compiler error: in change_file, at fortran/scanner.c:322 Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. -- Summary: ICE in December 6 version of gfortran when compiling a file with two routines that contain INCLUDE statements Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: michael dot a dot richmond at nasa dot gov http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34359
