 The `T3001-2` testcase fails on i386/Linux:

 {{{
 Wrong exit code for T3001-2(prof_hb)(expected 0 , actual 134 )
 Stderr ( T3001-2 ):
 T3001-2: internal error: Invalid object in processHeapClosureForDead(): 7
     (GHC version 8.5.20180419 for i386_unknown_linux)
     Please report this as a GHC bug:
 http://www.haskell.org/ghc/reportabug
 Aborted
 *** unexpected failure for T3001-2(prof_hb)
 }}}

 Closure type 7 is `CONSTR_NOCAF`, which is indeed invalid. Tracking this
 down will take some debugging.
