@bo_xu,

the check mentioned in chromium issue has been ported to OpenJpeg in r2897 (trunk),
part of issue 364 you reported. It's not done the same way but done anyway (this can
be seen on image 3.jp2).

With trunk r2908, I have no ASan issues in x86 or x64 on MacOS clang 3.5.0.

What revision of OpenJpeg are you using ?

There's one image that's not decoded by OpenJpeg which probably should (kakadu decodes
it properly).
