aspell still crash on almost all long Russian mistypes

[aspell-helper]

Lexan Palych olddaos\@sf created a bug report on 2005-11-11 15:35:13 UTC (Orig. from https://sourceforge.net/p/aspell/bugs/173)

Hello all!

My system is: i386, 4.10-STABLE FreeBSD, generic kernel.

I have aspell 0.60.4, and I tried to use it like a filter for processing very long Russian texts with 50% mistypes. Unfortunately, I wasn't able to do it due to its weird behaviour. It seems like it crashes on any sequence of glued words like
"unscrewyourdriver", "??????????????????", "???????????????" (regardless of language!).

I had compiled aspell with CFLAGS='-ggdb3 -g3' and CXXFLAGS='-ggdb3 -g3' and here I provide backtrace using gdb and coredump file.

This bug is not system dependant, i.e. I had achieved same results on amd64, and on many different 32-bit Intel-based FreeBSD systems. Here are sessions I had:

1) akosenkov@akosenkov:/home/akosenkov/> /usr/local/bin/aspell
--mode=none pipe @(#) International Ispell Version 3.1.20 (but really Aspell 0.60.4) ?????????????????? Segmentation fault (core dumped)

Here are backtrace using gdb: (gdb) bt #​0 0x2f481b in ??

Thank you in advance for any help on how to resolve this situation.

I'm looking forward for your reply and I'm ready to provide any additional information, that can help.

Can you please attach a small list of words which cause the crash so that I can see somthing other than "?????...".

Oh, I'm sorry that I had not managed to ensure, that Russian words were displayed correctly! In fact you can use any syntetic words like "unscrewyourdriver". I had performed _syntetic_ tests on words like this, and had found, that this bug is compiler-dependant. It cannot be reproduced using gcc 3.4*, and always observable when compiled using gcc 2.95.4.

I can add also "unscrewdrivers" - many words, length more then 12-13 can crash aspell.

If you want russian words: "копарнокопытное"

Ok, by compiling Aspell with 2.95 I can reproduce it. I will try to have it fixed for Aspell 0.60.5

The attached patch should fix the bug. Please try it out and let me know if it does or doesn't.
