 * status:  new => closed
 * testcase:   => typecheck/should_compile/T14363, T14363a
 * resolution:   => fixed


Comment:

 My patch fixes the loop.  The occurs-check problem was already fixed,
 perhaps by my `wc_insol` changes.  I've added tests for both.

 Richard I'd appreciate a quick look at the patch, but I'm pretty confident
 (following our discussion) hence committing.  Perhaps you can then close.
