Hi Jeff,
	Thank you for your report.
	Could you please send me your test code? I'd like test it.
	Thanks and regards,
Kui.

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.
