The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/9cd1f796acab342216f777537c2d0ded0fdd4645

commit 9cd1f796acab342216f777537c2d0ded0fdd4645
Author: Vladimir Levin <vmpstr@chromium.org>

oop: Use size_t as the kernel size for the matrix convolution filter.

This patch ensures to use size_t when computing the size of the kernel
for the matrix convolution filter.

The actual result of multiplication is int64_t, which can compare smaller
than (long)1000, but be extremely large when cast to size_t.
