Two questions:
1. what ./configure flags are you using?
2. what version of netcdf are you using?

I have a very simple unit test that is failing when I try to use netcdf4
parallel. The test creates a file, calls enddef, closes the file, then
trys to reopen it. Using netcdf 4.3.0 built with hdf5 1.8.11 I am getting
an assert error when I run this test,
3:testnetcdf4: nc4file.c:2858: NC4_open: Assertion `0' failed.
0:testnetcdf4: nc4file.c:2858: NC4_open: Assertion `0' failed.

The same test written in F90 instead of C passes.
#include <netcdf.h>
#include <mpi.h>
#include <netcdf_par.h>

int mype, npe;
int fh, ierr;
MPI_Init(argc,argv);

ierr = nc_create_par("try.nc",NC_MPIIO, MPI_COMM_WORLD, MPI_INFO_NULL,

MPI_Finalize();
