Sorry for not commenting on this sooner, I wanted to get #40 merged before hunting down other bugs.

I was able to reproduce this (although by now, not using the current version of AsyncRun); however, upon close inspection I'm not really sure if this error is quick-scope's fault.

The errors get thrown when processing quick-scope actions but they reference lines from AsyncRun. Specifically this line in AsyncRun_Job_Update and this one in AsyncRun_Job_AutoScroll. Not being an expert on how AsyncRun works I cannot say for sure, but I think these errors have something to do with AsyncRun trying to populate and modify the quickfix list while quick-scope is in the middle of a command.

Also interesting, the error Vim throws in this case (E523) references the 'secure' option, which doesn't seem to relate to this error.

Perhaps @skywind3000 has some insight on this?

[skywind3000]

Many plugins will populate quickfix window in a timer or in a background job such as ale, neomake and asyncrun. Background jobs and timers are designed for this.

Is there something about sandbox in quick-scope ?? Code running in sandbox is not allowed to execute many commands which will change buffer or execute shell commands. See:

:h sandbox

But asyncrun can't work without such things.

Similar phenomenon happens with other async plugins, e.g. ALE

To chime in, Also running into this issue with the following line in my vimrc:

autocmd FocusGained,BufEnter,CursorHold,CursorHoldI * if mode() != 'c' | checktime | endif

[skywind3000]

Auto-commands takes too much time or invokes some blocking function (I/O, sleep/wait).

[bradford-smith94]

The PR #81 that was just merged might also fix the E523 errors reported here. I don't know if that is the whole solution needed to make async plugins work with quick-scope but hopefully it is at least some progress.

I don't have a testing setup for this issue, but if someone interested in this could let me know whether or not the latest update helps I would be very appreciative.
