 Hi,

 with `-DDEBUG` in `GhcStage2HcOpts`, the test integerConstantFolding
 fails:

 {{{
 =====> integerConstantFolding(normal) 1103 of 3814 [0, 1, 0]
 cd ./lib/integer && $MAKE -s --no-print-directory integerConstantFolding
 </dev/null >integerConstantFolding.run.stdout
 2>integerConstantFolding.run.stderr
 Actual stderr output differs from expected:
