Segfault when trying examples.

Am I doing something wrong?

Here's some info on my setup.

No, that's a bug. Looks like infinite recursion when trying to perform the type check on 'fib'. I'll get a fix in tonight. Thanks for reporting it!

[tdenniston]

Should be working now.

[adamdecaf]

I'm still getting this after a clean and pull.

~/src/third-party/bish/examples $ ../bish fib.bish
segmentation fault: 11

[tdenniston]

I can't reproduce it now with the fib code you posted. Did you make clean and then make? If it persists, can you post a stack trace?

[adamdecaf]

Ah there we go. I forgot to clean, thanks!
