same input with PC ok but ARM crashed.

[MaeThird]

I used ncnn2mem tool to convert the model into head file.
With the same input image(1281x953 for this case),the PC is running well,but when I ported it to Raspberrypi board it crashed caused by the weird width and height of cnn processing. (the libncnn.a is compiled with NEON optimization sure it).
Here is what on Raspberrypi

And this's PC' output:

The printf code(moved to .cpp for print it out easily):

ex.set_num_threads(1); is set and openmp is closed for debug.
Is there anything wrong?Anyone help?
