Description László Németh 2013-12-16 12:40:15 UTC

CPython freezes using the following regex on a long word:

([a-z]+)+foo

A similar regex of the Hungarian grammar checking rules (1) freezes Lightproof grammar checking, and (2) trying to use other Python component (eg. LibreLogo) in LibreOffice will freeze LibreOffice, too.

Testing:

1. write the following line in a Hungarian document with Hungarian dictionary (it contains Hungarian grammar checking module) to test the work:

word ,

Lightproof will underline the space and comma.

2. freeze Python/Lightproof with the following line:

EEEJJJJJJJEEEEEEEJJJJJJJJEEEEEEEEJJJJJJJJEEEEEEJJJJJJJJEEEEE

3. check it:

word ,

Lightproof hasn't underlined the space and comma, yet.

4. freeze LibreOffice:

Click on one of the icons of the LibreLogo toolbar (Writer View->Toolbars....)
