[petsc-users] Possible Bug ?

[Sajid Ali]

Hi,

I see that src/mat/examples/tests/ex112.c is failing for petsc at 3.11.1
configured without complex scalars. With complex scalars everything works
fine.

The error I see is :
```
[sajid at xrmlite bugfix]$
./ex112

No protocol
specified

```

I came across this because I saw that MatMult was failing for a new test
related to a PR I was working on. Is this a bug ?
