Comment:

 `cabal09` has an intriguingly similar (albeit not reliable) failure:
 {{{
 =====> cabal09(normal) 249 of 6839 [0, 1, 0]
 cd "cabal/cabal09/cabal09.run" && $MAKE -s --no-print-directory cabal09
 CLEANUP=1
 Wrong exit code for cabal09()(expected 0 , actual 2 )
 Stderr ( cabal09 ):
 C:\GitLabRunner\builds\8fc0e283\0\ghc\ghc\tmp\ghcD256.o.tmp:
 renameFile:renamePath:MoveFileEx
 "\\\\?\\C:\\GitLabRunner\\builds\\8fc0e283\\0\\ghc\\ghc\\tmp\\ghcD256.o.tmp"
 Just
