Comment (by MikolajKonarski):

 Nope, and reducing the example reduces the problem, because it needs lots
 of specializations, so lots of code, to trigger. However, I guess one
 could construct a cheaper, artificial example with n simple functions
 specialized to m types and thus get n*m specializations (I only have 1--2
 types for each functions in my example, so I need lots of code). I wonder
 if we already have such example in GHC test suite. If so, we'd only need a
 variant where specializations is split between 2 modules and compare the
 time/heap as n and m grow.
