[bug #43454] Problem with Continuous Spell Checking

[Germán Arias]

Follow-up Comment #4, bug #43454 (project gnustep):

I think this two problems are related.

Backtrace when app crash:

Open Ink, select at menu Check Spelling Automatically and then write, notice
the last space, "Hello programme " (without quotes). Then in contextual menu
select "programmer". The app crash. Here the backtrace:

Program received signal SIGSEGV, Segmentation fault.

    at NSLayoutManager.m:1413
1413          NSRange r = NSMakeRange(glyph_pos + i,
glyph_run->head.glyph_length - i);

The other problem:

Open Ink, select at menu Check Spelling Automatically and then write "Hello
programme" this time without space at the end (without quotes). Then in
contextual menu select "programmer", the app hangs. This doesn't occurs if you
write only one word, for example "programm". Only if you write two or more
words. The odd thing here, is that auto complete also use
-replaceCharactersInRange:withString: and works OK. For example, open Gemas,
create a new Objective-C document, select at menu "Check Spelling
Automatically", and then write something like "#import NSMutabl" (without
quotes) and press Control-p to open the auto complete list, now select
something like NSMutableDictionary and this is inserted without problem.
