Comment:

 You can get all kinds of compiler-generated stuff in a `-hd` profile,
 because you're asking for closure descriptions.  The description of a
 thunk is the name of the thunk, which is often a compiler-generated name
 since the expression did not have a name in the original program, or is
 the result of inlining or transformation.  You could use `-hc -hdsat_sugg`
 for example to see what these closures were created by, or `-hy
 -hdsat_sugg` to see what type they have.

 BTW, is "critical" really appropriate for a profiling problem?
