Yes, it certainly fails for me:

$ ./build/tests/unit/test-io-channel-command -p /io/channel/command/fifo/sync
# random seed: R02S5134a426f643aeefdbe73921046b66da
# Start of io tests
# Start of channel tests
# Start of command tests
# Start of fifo tests
**
ERROR:../tests/unit/io-channel-helpers.c:152:qio_channel_test_validate: assertion failed: (test->readerr == NULL)
Bail out! ERROR:../tests/unit/io-channel-helpers.c:152:qio_channel_test_validate: assertion failed: (test->readerr == NULL)
Aborted (core dumped)

Daniel
