Hugo (0.153+) panics when building complex site

support
1

Hi everybody,

I’ve run into a strange issue with Hugo (version 0.153 and up) where it panics when building a fairly large site. I’m completely lost at where to start looking for a solution, since it only affects this particular project and doesn’t point to any part of the project itself. Even the error output is not consistent - I’ve included two examples - but hopefully somebody might know where to look, and what further details I can share to resolve the issue. Thanks in advance.

So, it’s a bug. I can see the “where it fails”, which should be enough to fix the issue, I guess…

There will be a new Hugo version out tomorrow (I think); I will try to get a fix for this by then.
