Comment (by ravi at bluespec.com):

 Running with -dcore-lint was helpful. It was a little odd in that several
 (unrelated) modules failed to compile the first-time through with -dcore-
 lint and --make, but succeeded on a reattempt. However, the module in
 question (IExpand.hs) consistently failed with -dcore-lint and the message
 pointed to a function that took an implicit parameter as an argument.
 Rewriting the function to no longer use that implicit parameter fixed the
 problem. I'm going to attempt to boil things down from there and see if I
 can come up with a simpler example that illustrates the problem.
