Neither have I.

What this particular CHICKEN test is doing is simply to generate
a function call with a LOT of arguments (it makes function calls
from 1998 up to 2048 arguments).  It could be the call or the function
itself that is the problem (though I think it's the function itself,
using varargs).

You can probably find information on how to file a bugreport on
their website, or you can ask on their mailinglist or IRC.

You could also file a bug with your operating system vendor and
let them push it upstream.   I'm not sure if that makes things
easier, and it may also make things harder.

Cheers,
Peter
