GHC HEAD panics in testsuite on OS X 10.8 with cc=Clang (using newest xcode 5 dev tools)
I got the following panics when I ran the GHC test suite per ticket #8148 (closed)
(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-stage2: panic! (the 'impossible' happened)

Actual stderr output differs from expected:
