Hi all.

sundials-5.8.0 is not compiling the example file examples/arkode/C_petsc/ark_petsc_ex25.c when i use PETSc-3.18.1:

PETSc 3.18 introduced an API change that breaks the example. You will need to either use an older PETSc version (< 3.18), use newer SUNDIALS, or possibly apply the changes in this commit 9ae48a1. We added support for PETSc 3.18 in the 6.3.0 release.
