I ran the sample tests, such that …  
**googlenet**

```auto
$~/opt/TensorRT-4.0.1.6/bin$ ./sample_googlenet 
Building and running a GPU inference engine for GoogleNet, N=4...
***Error in `./sample_googlenet': free(): invalid next size (fast): 0x0000000024ad2e90***

```

**sample\_int8**

```auto
$./sample_int8 mnist

```

**sample\_char\_rnn**

```auto
$ ./sample_char_rnn

```

**trtexec**

```auto
$ ./trtexec --deploy=/home/franksai/opt/TensorRT-4.0.1.6/data/mnist/mnist.prototxt --output=prob

```

My environment  
Device: GTX1080 Ti  
OS: Ubuntu 16.04  
CUDA: 8.0  
TensorRT: TensorRT-4.0.1.6
