 T10052.hs currently results in a runtime panic on interpreter-less GHCs:

 {{{
 =====> T10052(normal) 7 of 8 [0, 5, 0]
 cd ./T10052 && $MAKE -s --no-print-directory T10052    </dev/null >
 T10052.run.stdout 2> T10052.run.stderr
 Wrong exit code (expected 0 , actual 2 )
 Stdout:
 Makefile:9: recipe for target 'T10052' failed

 Stderr:

 when making flags consistent: warning:
     -O conflicts with --interactive; -O ignored.
 T10052: T10052: panic! (the 'impossible' happened)
   (GHC version 8.1.20160320 for x86_64-unknown-linux):
         unload: no interpreter

 Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

 make[1]: *** [T10052] Error 1

 *** unexpected failure for T10052(normal)
