Okay, turned out flycheck was basically irrelevant except that it
calls message a lot. And highlight-parentheses' only significance is
that it makes overlays all over the place. I have a simple reproducer,
run as
emacs -Q -l bug-21824.el -f 21824-trigger
The required circumstances appear to be that after a modification-hook
has been run and there is an overlay in the *Messages* buffer, the
message coalescing (the "[2 times]" thing) wrongly causes runs the
modification-hook of the overlay in the 1st buffer, but with
parameters from the *Messages* buffer modification.
A sample backtrace (I put a call to `debug' when the current-buffer is
incorrect).
Debugger entered: (#<overlay from 2 to 5 in foo.cpp> t 223 223 10
#<buffer *Messages*>)
(if (eq (current-buffer) (overlay-buffer overlay)) (message
"21842-mod-overlay(%s %s %s %s %s), buf = %s" overlay afterp beg end
len (current-buffer)) (setq 21842-repeat-message) (debug nil overlay
afterp beg end len (current-buffer)))
21824-mod-overlay(#<overlay from 2 to 5 in foo.cpp> t 223 223 10)
message("a message")
21824-trigger()
