 I got the following panics when I ran the GHC test suite per ticket #8148

 (using xcode 5 CLI dev preview tools released as of  august 21st on OS X
 10.8)


 =====> ghcilink003(normal) 889 of 3736 [8, 195, 0]
 cd ./ghci/linking && $MAKE -s --no-print-directory ghcilink003
 </dev/null >ghcilink003.run.stdout 2>ghcilink003.run.stderr
 Wrong exit code (expected 0 , actual 2 )
 Stdout:

 Stderr:

   (GHC version 7.7.20130822 for x86_64-apple-darwin):
