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 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.
