[petsc-dev] Bug in example code

[Tim Gallagher]

Hi, 

I just cloned the petsc-dev branch for the first time and built it with GCC with both release and debug options and the tests during make test worked fine. I then built it with Intel with release options and the tests worked. Then I compiled with debug options and one of the tests generates an error:

Possible error running Fortran example src/snes/examples/tutorials/ex5f with 1 MPI process
See http://www.mcs.anl.gov/petsc/documentation/faq.html
forrtl: severe (408): fort: (2): Subscript #1 of the array LX_V has value 15092 which is greater than the upper bound of 1

I am using:

Intel(R) Fortran Intel(R) 64 Compiler XE for applications running on Intel(R) 64, Version 12.1.1.256 Build 20111011
Copyright (C) 1985-2011 Intel Corporation.  All rights reserved.

and petsc was configured with:

./configure PETSC_ARCH=linux-intel-debug --prefix=/opt/petsc/intel/2011.sp1.1/debug --with-make-np=12 --with-clanguage=C++ --with-c-support=1--with-fortran-kernels=1 --with-shared-libraries=1--download-scalapack=yes --download-parmetis=yes --download-metis=yes --with-imagemagick=1 --download-sundials=yes --download-mpi4py=yes --download-petsc4py=yes --download-boost=yes --with-hdf5=1 --with-hdf5-dir=$HDF5_DIR --with-imagemagick=0 --with-shared-libraries --with-debugging=no COPTFLAGS='-g -C -traceback -fpe0 -check noarg_temp_created -fp-stack-check -check uninit' FOPTFLAGS='-g -C -traceback -fpe0 -check noarg_temp_created -fp-stack-check -check uninit'

I am going to try looking for the problem, but since this is the first 10 minutes I've looked at the code, it will probably take me a lot longer than somebody else to find the problem. Let me know if there's anything I can do to help track down the problem. 

Thanks,

Tim
