Not sure if that is used in your build, but in x_display_info (xterm.h)
I see a number of struct frame pointers that are not fixed in fix_frame,
starting with

  struct frame *x_focus_frame;

And if it's not that display info that is being used, I'd bet a small
amount that whatever is actually used (pgtk_display_info?) has a similar
problems.

(Can't fix this myself, sorry, I only have macOS.)
