NSException Description:

*** Terminating app due to uncaught exception 'NSRangeException', reason: 'NSMutableRLEArray objectAtIndex:effectiveRange:: Out of bounds'

Something logged just before crash:

Removed Indexes:<NSMutableIndexSet: 0x16695290>[number of indexes: 436 (in 2 ranges), indexes: (3429-3618 3621-3866)]

I have not been able to find a trigger for this crash yet.

[ndrewh]

@Anviking I have been able to reproduce the crash with the older version (before the fixes yesterday). With the fixes, attempting to reproduce the crash does not crash it anymore. Instead the text is unhighlighted (just white), and this is logged:
Removed Indexes:<NSMutableIndexSet: 0x17574f90>[number of indexes: 306 (in 2 ranges), indexes: (8376-8589 8592-8683)]

[Anviking]

@NerdYouDontKnow This is very interesting! 😄

If we look at the relevant parts in the scope:didChangeIndexesFrom:to:-method.

    // This line was added in 0241655de96c2c14b1f3ee9dde19015bfd7b4009
    removedIndexes = [removedIndexes intersectionWithSet:[NSIndexSet indexSetWithIndexesInRange:NSMakeRange(0, scope.textStorage.length)]];

    if (removedIndexes) {
    [removedIndexes enumerateRangesUsingBlock:^(NSRange range, BOOL *stop) {

        // This was self.textStorage before 8ed1aa4e6b96d0e2b2b99c5c946d21e3e3afa056
        [self tokenizeTextStorage:scope.textStorage withRange:range];
    }];
} 

When indexes are cleared (removed) they should be re-tokenized. Apparently they are not, which might indicate that this is related to #16 and that self.textStorage was set to nil or possibly another textStorage. If this is the case this should work now because of 8ed1aa4.

Before 0241655 it crashed because it tried to refresh indexes that were out of bounds to the textStorage. Somehow the block-comment pattern must have been performed twice and found less block-comments the second time. Did something remove text from the textStorage?

If the textStorage was not edited, maybe, maybe the first crash was because, as stated earlier, self.textStorage was set to nil or possibly another textStorage.

[ndrewh]

@Anviking Yes, I repeatedly use [myTextView setText:@"New Code"], so I think in that way I am editing textStorage.
