I imported https://www.mediawiki.org/wiki/VisualEditor/Feedback into Flow with the LQT importer (plus some small changes for https://gerrit.wikimedia.org/r/#/c/172925/ that are probably not relevant to this bug). The import crashed (bug 73638), but a lot of stuff was already imported by then. However, when I visit it, I get: "Fatal error: Maximum function nesting level of '200' reached, aborting" The stack is https://phabricator.wikimedia.org/P98 . It seems that the nesting level of a topic may influence the nesting level of the function stack, and cause it to go over the limit.
This error comes from xdebug.max_nesting_level. XDebug is not enabled in production, so we shouldn't have to worry about this. I confirmed it can be worked around locally by raising the limit or switching to HHVM.
