memory leak while encoding webp: 6.7.6 - 6.7.9-7

[zhcn381]

hi magick,
we are using IM6.7.6 in our production system. And we noticed that while doing the encoding of webp there is a memory leak. I've checked the latest version(6.7.9-7) and finding that the problem still exists. Following is the patch, pls check it, thx.

Code: Select all
