Crash at usage of GaussianBlur with small images

Hello, I have been facing an issue when using method GaussianBlur.

If used on images smaller than (around) 230 px of width the library will crash systematically with error like following:

Error: Output buffer gaussianblur is accessed at -384, which is before the min (0) in dimension 1
SIGABRT: abort
PC=0x7f896a72000b m=5 sigcode=18446744073709551610

Increasing the image width at 240px "solves" the issue. Seems that Boxblur is impacted too.
