Check failed: data_ when run in cpu model

[cslxiao]

Under the same setting, gpu model runs right but cpu model yields the following error:
I0914 03:57:20.528827 26625 caffe.cpp:252] Running for 1449 iterations.
F0914 03:57:20.597383 26625 blob.cpp:163] Check failed: data_

ps: I could not run in gpu model because of the limit of memory.
