seg fault caused by nonblocking reads of scalar variables

Using pnetcdf 1.2.0, I get a seg fault during ncmpi_wait_all if I try to read both scalar and dimensioned variables at the same time.  I'm using ncmpi_iget_vara_XXX calls followed by ncmpi_wait_all.  I can read 1 or more dimensioned variables.  I can read 1 or more scalar variables.  But once I try to mix scalar and dimensioned, I get the seg fault during ncmpi_wait_all.  If I use the blocking calls, everything works okay, but then I'm only reading one variable at a time.

Any ideas?  Thanks.

Jeff
