Ok, great, so we have a handle on this problem. > I think there are a couple other places, maybe in the MPI stuff, where > function pointers and data pointers are conflated, though I think they > are also easy enough to replace. In the nightly tests are only very few warnings of that type left. Only 11 files affected with about ~7 warnings each on average: vec/pf/impls/constant/const.c mat/matfd/ftn-custom/zfdmatrixf.c mat/impls/mffd/ftn-custom/zmffdf.c ksp/pc/impls/tfs/comm.c ksp/pc/impls/tfs/xxt.c ksp/pc/impls/tfs/xyt.c ksp/ksp/interface/ftn-custom/zitfuncf.c snes/interface/ftn-custom/zsnesf.c snes/utils/dmsnes.c ts/interface/ftn-custom/ztsf.c ts/utils/dmts.c:65 Please let me know if I can be of any help.
