		stuntmouse on Oct 23, 2009 \| parent \| context \| favorite \| on: Scheme hits the App Store I've reproduced your crash. The issue is that you're using define within a nested REPL, which isn't supported [1]. However, a segfault is really not acceptable. I'll file a report for this.

Relevant section: "Note that some special forms (define in particular) can only be evaluated in the global interaction environment."

I'm fairly sure that the nested repl 'define' being allowed at all is a fairly recent change, I seem to recall just getting an error when trying to define in a nested repl in 4.4.x.

Right, it looks like a regression in 4.5.*. 4.4.4 is fine.
