Strange... I wonder if we're getting hit by the issue pointed out to Tom -
namely we should cap the ldevs iteration in platform::platform() to the value
returned by the second call to pipe_loader_probe. Reason being that second call
to pipe_loader_probe() may return smaller count (device has gone missing,
enomem, other).

Alternatively can someone pin-point the commit that causes this (note you might
need to cherry-pick patch in comment 1 to fixup commit ff9cd8a67ca).

Thanks
