Buffer overflow detected when using matplotlib

Dear all,

After I installed CUDA, the following code started displaying “buffer overflow detected”.
If I remove “esa_snappy” it works fine.

import esa_snappy
from esa_snappy import ProductIO, GPF, HashMap
from esa_snappy import GeoPos, PixelPos, Rectangle
from esa_snappy import Product,ProductUtils,WKTReader

import numpy as np
import matplotlib 
import matplotlib.pyplot as plt

x = np.linspace(0, 2*np.pi, 500)
plt.plot(x,np.sin(x))
plt.show()

Any help would be appreciated.
All the best,

Zuiko
