Comment 12 Miroslav Lichvar 2014-02-18 13:57:06 UTC 
I can reproduce it with

dialog --file <(echo aaa) --yesno 15 50

The latest upstream dialog (20140112) seems to crash too. CCing upstream maintainer.
Comment 13 Thomas E. Dickey 2014-02-19 01:09:46 UTC 
I see - basically the problem is that the cases I tested all
had more than one token (so the adjustment-loop is wrong).
will fix...
Comment 14 Thomas E. Dickey 2014-02-20 01:25:56 UTC 
I've uploaded a fixed version.
Comment 15 Miroslav Lichvar 2014-02-20 13:30:04 UTC 
Thanks, Thomas.
