Seems that this issue exists in src\lib\openjp2\j2k.c. I only roll back this 
file to some version before r2883. This issue doesn't happen.

Here's the image extracted from the pdf

Original issue mentions Chrome 64 bits, All OS.
I can't reproduce the issue using trunk r2997 on MacOS 64 bits. The image is 
decoded properly.

The file 'size-guide.pdf' is shown properly by XPDF.

But the file issue473.jp2 is brutal: 5167 x 6792 .
