Hello,
With the new version 3.0.0-p8, if I assign a value to the dummy in
MyKSPConverged at the end of src/ksp/ksp/examples/tutorials/ex2f.F, I get a
segmentation fault (this didn't happen with version 2.3.3-p13). Any idea why?
$ tail ex2f.F
else
flag = 0
endif
ierr = 0
dummy = 0
end
$ ./ex2f -my_ksp_convergence
