Bug: xphoto::Inpaint crash without exception [closed]

edit

Hey guys,

I compiled opencv with contrib module. It works well, however as soon as I try to use xphoto::Inpaint method the code crashes without an exception. Datatype of the mat is CV_64F. All inputs are correct.

Further informations: OpenCV 3.3.1 Linux 64 Bit Contrib 3.3.1 Compiler: GCC

Additionally I ran valgrind and here is the output. I have no experience with it so far, so I don't know if it helps.
