## Test output (expected 'No Errors'):

In b56f5da:
ROMIO: fix stack fault in NBC I/O

This is currently a workaround to avoid weird errors, e.g., stack
fault, occurred in the NBC I/O implementation on Linux. When the host
OS is Linux and aio-lite is not used, a blocking ADIO function is used
in the NBC I/O implementation.

Fixes #2201
