Subject: [Rd] tests/ok-errors.R ## bad infinite recursion
Message-ID: <20080522172006.GC2895@sadie.duo>

I've come across a handful of tests that
fail at our site.  I consider this one the
worst because the process does not return.

The patch below simply bypasss the test,
but the errors in the out file are included
as well. I suspect this is due to more or
tighter ulimits on this system.

But I'm not sure if this is result of
different expectations (kernel/userland) of
what should be done in the curcumstance.
