LibreOffice crashes when interacting with Danish and Swedish thesauri

[Gunnar Hjalmarsson]

[Impact]

When running in Danish or Swedish, and when both the hunspell dictionary and the thesaurus are installed, LibreOffice crashes when right-clicking highlighted text. The issue has been fixed in hunspell 1.3.3:

https://github.com/hunspell/hunspell/commit/d660d4b1b4ecb341fe7d9966e5e593ae11396e2d

The proposed upload cherry picks that commit, another related commit, and the changes in git to affixmgr.cxx and affixmgr.hxx up to the time for those commits.

[Test Case]

The issue seems to be limited to 32 bits installs. Users of Ubuntu, Xubuntu and Linux Mint with 32 bits architecture have reported the issue, and when present, it's obvious from the description above how to reproduce the bug.

[Regression Potential]

Since the code has been present in hunspell 1.3.3 for quite a while, the regression risk should be low.

This is the patch which is proposed for trusty-proposed:
https://launchpad.net/~gunnarhj/+archive/ubuntu/hunspell-thesaurus

[Gunnar Hjalmarsson (gunnarhj)]

Problem:
The PPA version 1.3.2-6ubuntu2.1~ppa4 improves the situation slightly, but it's not sufficient to prevent these crashes. At the same time we have found that hunspell 1.3.3-3 from the vivid repository can be installed in trusty without any dependency complaints, and doing so fixes the issue completely.

So would uploading hunspell 1.3.3-3 to trusty as an SRU, in order to fix this bug, be an acceptable option?

Finally we figured out what to include in the patch, without upgrading the whole package to 1.3.3. Even if there is a PPA, I attach a patch, so the changes are shown more clearly.

I have successfully installed libhunspell-1.3-0 1.3.2-6ubuntu2.1 from trusty-proposed onto my Ubuntu trusty i386 installation. The reported type of crash, when using LibreOffice Writer, does not happen any longer.
