Re: ProjectCenter Editor parenthesis highlighting segfault

[address@hidden]

Hello,

 

i thought that accessing an array out of it's dimension would lead to a segfault in the header of the loop.

 

But reading your last mails I compiled the code with the original _expression_ in the head of the for-loop

 

and put NSLog(@"---i=%i---",i) right at the beginning of the body.

 

 

 

- (void)unhighlightCharacter: (NSTextView *)editorView
{
int i;
NSTextStorage *textStorage = [editorView textStorage];

 

[textStorage beginEditing];

 

// if (isCharacterHighlit)
for (i = 0; (highlited_chars[i] != -1 && i < 2); i++)
{
NSLog(@"---i=%i---",i);
NSRange r = NSMakeRange(highlited_chars[i], 1);
// NSRange r = NSMakeRange(highlitCharacterLocation, i);

 

...

I expected that i could never get greater than 1 in the body of the loop as the boolean _expression_

 

must return false when i reaches 2. I ran this several times and i always reaches 3 bevor the segfault

 

occurs.
