It looks like the indentation for function arguments is screwed up when the line gets to long. No arguments needed for astyle to reproduce the problem.
void doSomething() { m_thismustbethatlong = my_func_12345678(m_BookmarkManager, i18n("&Bookmarks"), this); m_thismustbethatlong = my_func_123456789(m_BookmarkManager, i18n("&Bookmarks"), this); }
Tested with 2.04 from openSUSE and svn HEAD (r461)
Increase the value of max-instatement-indent.
