This is almost certainly an indexing error, I suggest looking carefully
at the definition in struct _MatOps.  Your error message has that line
number because that is the end of the initializer and GCC's parser
doesn't retain the information required to easily produce a better
message.  Clang is better in this case, you should see something like:

mpidense.c:1580:8: warning: incompatible pointer types initializing 'PetscErrorCode (Mat)', expected 'PetscErrorCode (*)(Mat, Mat, PetscReal, Mat *)'
      [-pedantic]
       MatConjugate_MPIDense,
