From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; fr; rv:1.7.8) Gecko/20050623 Fedora/1.0.4-5 Firefox/1.0.4 Description of problem: A simple program leads to Internal Error at (1): error_char(): Error buffer overflow however the program itself doesn't seems to be the culprit, but rather the preprocessor lines as when I remove a preprocessor line the compilation proceed, and there are many warnings that seems to be related with preprocessing. Here is the code: SUBROUTINE SZREAD() integer luncz luncz = 0 IF(LUNCZ.NE.0) WRITE(*,*) 'hello' END I attach the file which also has the preprocessor lines The whole output reads: [dumas@chapelle bug_reports]$ gfortran -c szread.F -o truc.o line-map.c: file "/home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/sz/szread.F" left but not entered line-map.c: file "/home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/sz/szread.F" left but not entered Warning: /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/zmachfix.inc:3: file /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/zmach.inc left but not entered Warning: /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/zmachfix.inc:4: file /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/pilot.h left but not entered Warning: /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/hcmail.inc:3: file /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/czsock.inc left but not entered Warning: /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/czoptd.inc:4: file /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/czopts.inc left but not entered Warning: /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/czoptu.inc:8: file /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/czopts.inc left but not entered In file /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/czoptu.inc:5 Included at /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/czoptd.inc:6 Included at /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/czopts.inc:4 Included at /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/hcmail.inc:5 Included at /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/czsock.inc:2 Included at /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/zmachfix.inc:6 Included at /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/zmach.inc:2 Included at /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/cspack/pilot.h:3 Included at /home/dumas/rpmbuild/BUILD/cernlib-2005/2005/src/packlib/cspack/sz/szread.F:3 IF(LUNCZ.NE.0) WRITE(*,*) 'hello' 1 Internal Error at (1): error_char(): Error buffer overflow [dumas@chapelle bug_reports]$ Version-Release number of selected component (if applicable): gcc-gfortran-4.0.1-2 How reproducible: Always Steps to Reproduce: 1.compile the attached file 2. 3.
