yes, the repl is not that stable. it is possible to segfault it by 
splitting simple commands in multiple lines a couple of times, deleting 
back the previous line, and deliberately messing up parentheses. i was 
experiencing crashes this way, but haven't found the cause yet.

probably it cannot be reproduced this easily, but i attached the 
keypresses on my macbook which causes a segfault if played back.

backtrace:
