Package: petsc2.0.29-examples
Version: 2.0.29-6
Severity: normal
When running tests on PPC, there are a number of integer errors which could
indicate signed/unsigned char issues. Then in sles/examples/tutorials, it
seems to infinite loop in runex13, not sure what to make of that.
There are a boatload of errors with testfortran as well. See below.
Here are the diffs from testexamples_1 in mat/examples/tests:
