In my case, when caffe model finishs predicting an image. There is the below error:

F0910 15:09:52.590445 21913 syncedmem.hpp:30] Check failed: error == cudaSuccess (11 vs. 0) invalid argument
*** Check failure stack trace: ***
Aborted

It comes from CUDA_CHECK(cudaFreeHost(ptr)); in syncedmem.hpp.
Everything else works well. Any ideas for fixing this? I use latest code in the master.

I'm using Ubuntu 14.04, NVIDIA driver 352.41, Cuda 7.5 and CuDNN v2.
