problem with PetscSynchronizedFPrintf (fwd)

[Satish Balay]

Looks like this could be related to changeset 9e3fbe04a926

--> mprint.h <--

-  char        string[QUEUESTRINGSIZE];
+  char       *string;

So now strings needs to use malloc()/free()?

Matt - you can reproduce this issue with dm/ao/examples/tests/ex7.c
