nope :/

commit: af800c4b1bfc795de4ad4ac5a37122c1f3a9a852 build: 2014-04-09
,echo '/R' | r2 /usr/bin/aspell 
 -- Default scripting languages are NodeJS and Python.
Segmentation fault

[zonkzonk]

also: /R in debug mode hangs and eat 100%CPU Ⓜ️ (do we need /R with -d at all ? )

[zonkzonk]

cannot reproduce in 1ccd783

cool! Thanks!1 :)
