Comment (by simonpj):

 `catch` is ''not'' strict in its argument.  Its argument is a function;
 `catch` just guarantees to call that function.  So yes `build (...)` is
 sure to be evaluated, but GHC doesn't aggressively evaluate things as
 early as possible.  It just uses strictness info to avoid building thunks;
 and none are built here.  So I think it's fine.

 Might be wroth fixing the test though.

 Thanks for the accurate diagnosis.

 Simon
