commit d3fd3fea52458793122adc8ef580ddeca2d4dfe5
Author: Herbert Valerio Riedel <hvr at gnu.org>

    Mark GHC.Stack.Types Trustworthy
    
    GHC can't infer this module safe due to the `GHC.Types (Char, Int)`
    and the  (dummy) `GHC.Integer ()` import.
    
    If only `GHC.Types` was marked Trustworthy or Safe...
    
    (cherry picked from commit 91ee5090f1e3f43e9e803cf7005a7f3357e58377)
