I fixed my code error with valgrind and now I see the same thing (appended) as before (eg, valgrind does not seem to help). I'm suspecting that MatConvert is messed, but I will try not deleting this matrix and see what happens.

I couldn't agree more about using the modern versions of Fortran! Oh the fights we've had here about that one... I thought I read somewhere that petsc F90 wasn't working correctly/had limited support, but perhaps that was old or incorrect. I think I got that impression here: http://www.mcs.anl.gov/petsc/petsc-3.1/docs/manualpages/Sys/UsingFortran.ht… I will recompile it with the F90 turned on instead.

The lines subroutine FormInitialGuess(X,ierr) implicit none #include "ex5f.h" ! Input/output variables: Vec X PetscErrorCode ierr ! Declarations for use with local arrays: PetscScalar lx_v(0:1) PetscOffset lx_i Vec localX will break that because we access outside th lx_f(0:1) array. Our Fortran examples that use F77 have to violate the array bounds so must be compiled without that checking. The Fortran 90 examples like ex5f90.F use F90 constructs and thus don't violate bounds.

Tim, You must have array bounds checking turned on for Fortran with the Intel debug version. The lines subroutine FormInitialGuess(X,ierr) implicit none #include "ex5f.h" ! Input/output variables: Vec X PetscErrorCode ierr ! Declarations for use with local arrays: PetscScalar lx_v(0:1) PetscOffset lx_i Vec localX will break that because we access outside th lx_f(0:1) array. Our Fortran examples that use F77 have to violate the array bounds so must be compiled without that checking. The Fortran 90 examples like ex5f90.F use F90 constructs and thus don't violate bounds. If you plan to use Fortran it makes sense to use the F90 version; after all 2011 >> 1977 :-) Barry On Nov 23, 2011, at 12:04 PM, Tim Gallagher wrote: > 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 need a uni regression test apparently. After you do the "make all test" on PETSc do "make alltests" and it should run all the tests that run on one process. Something is wrong with your reference counting likely here. Does this work with --with-debugging=0? I would run debug version with valgrind first. Then debug version in debugger.

Bug in example code

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 Image PC Routine Line Source libirc.so 00007F4245C589AA Unknown Unknown Unknown libirc.so 00007F4245C574A6 Unknown Unknown Unknown libifcore.so.5 00007F4240A5B6FC Unknown Unknown Unknown libifcore.so.5 00007F42409CEDA2 Unknown Unknown Unknown libifcore.so.5 00007F42409CF323 Unknown Unknown Unknown ex5f 0000000000403F58 forminitialguess_ 294 ex5f.F ex5f 0000000000403719 MAIN__ 224 ex5f.F ex5f 00000000004028AC Unknown Unknown Unknown libc.so.6 00007F42401AB23D Unknown Unknown Unknown ex5f 00000000004027A9 Unknown Unknown Unknown 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.
