I don't think so, we have tracing in place to detect mismatches. But as soon as I switch the tracing on, the error disappears... Same if I add a counter or print statements before and after EventBegin/End. Looks like a memory corruption problem, maybe nothing to do with petsc despite the error message.

Therefore I've tried adding it to src/snes/ex5f90.F90 and that also works fine. It seems I cannot replicate the problem in a small example, unfortunately. We cannot replicate it here.
