train model and test model also encounter the problem free(): invalid next size

Hi,
when I input `python main.py --dataset mnist --input_height=28 --output_height=28 --c_dim=1 --is_train`
it can run until epoch[24] and then it output:Error in python': free(): invalid next size (normal): 0x00000000011c5c10
when I input `python main.py --dataset mnist --input_height=28 --output_height=28 --c_dim=1`
it cannot run and output: Error in python': free(): invalid next size (normal): 0x00000000011c5c10
Could anyone help me?

Start by reproducing the reported failure with the two `python main.py` commands for MNIST, comparing training and test-mode behavior and the crash around epoch 24. Inspect `main.py` and the TensorFlow execution path to determine the source of the `free(): invalid next size` error; done means the commands run without the reported memory error and the relevant behavior is covered by a regression check.
