 This occurred while running our sizeable program I have no idea what the
 program was doing when this error was encountered but the compiler asked
 me to report it here:

 programName: internal error: PAP object entered!
     (GHC version 8.4.3 for x86_64_unknown_linux)
     Please report this as a GHC bug:

 Aborted

 I don't have a way to reproduce this yet.
