Bus Error while trying to run the ffi_closure example in the documentation...

[Nathan Rajlich <nathan@tootallnate.net>]

Hey all,

So I'm trying to run the ffi_closure example from the libffi
documentation (the one that wraps fputs() ). When trying to run the
program, I get a "Bus Error: 10" and the program crashes.

This is on OS X 64-bit (Lion). Put through gdb, this is what I get:

∞ ~/node-ffi/deps (gyp) $ gdb --args ./out/Debug/test

Thanks for looking, any thoughts would be appreciated! Cheers!
