Bug#644506: hunspell: crash with some morphological fields combination

Package: hunspell
Version: 1.2.14-4
Severity: important
Tags: fixed-in-experimental

Dear Maintainer,

hunspell crash on some wrong words if some morphological fields combinations are present in the affix file. Note that you have crash only on some wrong words.

Note that this crash can be reproducible in (i think all) applications that use hunspell spellchecker (i.e. LibreOffice, that I have tested: you have a crash if you right click at some red underscored words).

Workaround: if you remove all morphological fields from affix file there is no more crash.

This bug seem to be fixed with hunspell 1.3.2, please let it go to sid and testing and let all application depend on it.

I reported this bug to let people understand why some applications crash in spell checking tasks and how to resolve it (workaround).

Steps to reproduce the crash are the followings:

1) create b.aff file as:

2) create b.dic file as:

3) create test file  as:

4) generate the crash
$ hunspell -d b test
