[petsc-users] Segmentation fault when using matlab interface

[De Groof, Vincent]

Well, basically the simplest program I have the problem with is initializing and finalizing petsc.

% Set environment variables.
setenv('PETSC_DIR', '/usr/local/petsc-3.3-p2/')
setenv('PETSC_ARCH','arch-linux2-c-debug')

% Call PETSc.
PetscInitialize();
PetscFinalize();


thanks.

Betreff: Segmentation fault when using matlab interface

Hello,

I'm trying to use the Petsc objects directly from Matlab. However, when testing the examples in the /bin/matlab/classes/examples/tutorials-directory, I get a segmentation fault (core dump) error. Unfortunately, I don't get more information then this. After running some different situations, I know the following:
I ran matlab both with and without desktop. The only error message I get is the segmentation fault. Sometimes it doesn't give the segmentation error after running the example. If so, it will cause a segmentation fault upon entering the next command in the matlab shell. If I quit matlab immediately after running an example without segmentation fault, my unix shell will hang.


I know it's kind of vague, but this is all I know now. Any suggestions to look at to solve this problem?


thanks.
