[plt-scheme] Check-error

Hello Jos,

if I understand your code correctly, the problem is that you return
values from your coroutine to an explicit continuation, but you throw
the error from the coroutine to an implicit error continuation that is
not associated with the return continuation you would use in case
there were no error. Hence your code probably throws the error in the
context of a different test case than the one that actually invoked
the coroutine.

Ciao,
Thomas
