Some pages do not display due to tables

There is a really odd issue since my update to PHP7, where having too many or a specific combination of images in a table will cause that page to not display properly.

e.g. this breaks

(note that there are comments starting with - which would be removed during an actual test)

{| class="single-row"
|- valign="top"
| [[image:Windows-3.1-logo-white-background.png| 60px|link=Windows 3.1|Windows 3.1x]]
| [[image:Windows-9598-logo-white-background.png|60px|link=Windows 9x |Windows 9x]]
| [[image:Windows-XP-logo.png|                   60px|link=Windows XP |Windows XP]]
| [[image:Windows-7-logo.png|                    60px|link=Windows 7  |Windows 7]]
| [[image:Windows-8.1-logo.png|                  60px|link=Windows 8.1|Windows 8.1]]
- For some reason, this stopped working within this block
| [[image:Windows-10-logo.png|                   60px|link=Windows 10 |Windows 10]]
- This will work if placed without a comment, like so:
| [[image:Windows-10-logo.png|                   60px|link=Windows 10|]]
|}

The broken line works standalone like so:

{| class="single-row"
|- valign="top"
| [[image:Windows-10-logo.png|                   60px|link=Windows 10 |Windows 10]]
|}

The page I need help with: [log in to see the link]
