Gaussian Blur with type CV_32FC1 causes invalid memory access inside IPP code #11303
Description
I have a reproducible bug which fails in libippiw. This seems to be not open source, but a binary library.
I was not aware that "open" cv meant mostly open. Is there source that can be used to debug this problem? Here is a gdb stack trace.

If there is a new version of libippiw, or a convenient way to submit a bug to someone who has the source code, I will be happy to describe the build and test procedure.
