hi, I just pulled the latest next branch and found that the PetscSF stuff doesn't appear to work in Fortran anymore for me. When I run the ex1f example it gives: [0]PETSC ERROR: ------------------------------------------------------------------------ [0]PETSC ERROR: Caught signal number 11 SEGV: Segmentation Violation, probably memory access out of range [0]PETSC ERROR: Try option -start_in_debugger or -on_error_attach_debugger [0]PETSC ERROR: or see http://www.mcs.anl.gov/petsc/documentation/faq.html#valgrind [0]PETSC ERROR: or try http://valgrind.org on GNU/linux and Apple Mac OS X to find memory corruption erro rs [0]PETSC ERROR: likely location of problem given in stack below [0]PETSC ERROR: --------------------- Stack Frames ------------------------------------ [0]PETSC ERROR: Note: The EXACT line numbers in the stack are not available, [0]PETSC ERROR: INSTEAD the line number of the start of the function [0]PETSC ERROR: is given. [0]PETSC ERROR: [0] PetscSFBcastBegin_Basic line 922 /home/acro018/software/PETSc/code/src/vec/is/sf/impl s/basic/sfbasic.c [0]PETSC ERROR: [0] PetscSFBcastBegin line 972 /home/acro018/software/PETSc/code/src/vec/is/sf/interface/ sf.c [0]PETSC ERROR: --------------------- Error Message ----------------------------------------------------- And the same thing happens with my own code. Should this example still work? Or is there something else I need to do? I did make allfortranstubs and make. - Adrian -- Dr Adrian Croucher Senior Research Fellow Department of Engineering Science University of Auckland, New Zealand email: [email protected] tel: +64 (0)9 923 4611
