Fuzz crahes XCode 7

[achernoprudov]

When I'm trying to correct a misspelled word by deleting with backspace Fuzz crashes my XCode 7.
Here is some part of crashreport.

+1 was just about to come report same crash, same out-of-bounds error (NSMutableRLEArray objectAtIndex:effectiveRange:runIndex:: Out of bounds)

[egold]

I believe crash happens in this method: https://github.com/FuzzyAutocomplete/FuzzyAutocompletePlugin/blob/master/FuzzyAutocomplete/DVTTextCompletionListWindowController%2BFuzzyAutocomplete.m#L121

[egold]

Interestingly, after removing FuzzyAutoComplete, base Xcode autocomplete crashes when backspacing past the 5th character. I think this may be an Xcode 7 issue, not FAC's issue.

This might be coincidental, but I noticed if I typed a few characters like [super viewDidL and wait a few seconds, the crash hasn't happened since. Maybe Xcode is lazy-building some index for autocomplete? Fingers crossed...

[Brok3nHalo]

Do you guys happen to have SCXcodeMiniMap installed as well?

I had this same crash and removing FuzzyAutoComplete also didn't help, but then someone I work with had the same issue and we only had two overlapping plugins and Fuzzy wasn't one of them. After uninstalling MiniMap I re-installed FuzzyAutoCOmplete and haven't had crash in over an hour.

@Brok3nHalo Thanks!! Removing SCXcodeMiniMap has solved the issue for me.

[saltwat5r]

I've just removed SCXcodeMiniMap, but this not resolved problem.

[yuzupup]

+1 to experiencing this. Not sure of the exact circumstances... I've since turned Fuzzy off because when it crashes, I lose work :(

[egold]

It's a problem with vanilla Xcode too. Even after completely removing Alcatraz, I still get this crash. The workaround I'm using is to set Xcode prefs to not use autocomplete except when I press the Esc key. So lame.

[BillZong]

@Brok3nHalo Thanks a lot. It confuse me some how until I remove the SCXcodeMiniMap.

[yuyao110120]

Hide MiniMap has solved the issue for me.

[slazyk]

Is this still happening in 7.1? If yes, does removing SCXcodeMiniMap help?
