can't press ret without error

can't press ret without error

[Samuel Wales]

in maint.

for a very long time, i have done (setq
org-element-use-cache nil) because i kept getting errors or
buffer corruption.

now, errors occur even with that setting.

all i did was press return.  this followed trying to comment
a blank line (which i wish emacs would just do).

i cannot do a thorough bug report or q/a at this time but
thought this might be useful.

Debugger entered--Lisp error: (error "Stack overflow in regexp matcher")
  re-search-forward("^\\(?:\\*+
\\|\\[\\(?:[0-9]+\\|fn:[-_[:word:]]+\\)\\]\\|%%(\\|[

It seems you are using very long lines. 

In particular one of them is ambiguous and the parser has to match too
much (hence the stack overflow) to decide what is that line.

It would help to see that line. Could you make an ECM?

Thank you.

Thinking about it, trying to evaluate

  (re-search-forward org-element-paragraph-separate nil t)

in various places may give you a clue about the problematic line.
