That would be
$  clang --version
clang version 3.2 (http://llvm.org/git/clang.git 
b9d2b3b8edf7a0dc56e55acb1cf87338d5648daa) (http://llvm.org/git/llvm.git 
Target: i386-pc-linux-gnu
Thread model: posix

I forgot to mention (but I guess you found out), that the file for 
minimization after all those errors was empty. Another consideration is 
if the emptiness of the file might have been caused by the perl warning 
I referred to in creduce-dev (email sent today).

The minimization script was:

$HOME/p4ws/pm18_binutils/bc/gcctest/lib/timeout.sh -t 2 
-Os test.i &> /dev/null
if [ "$?" -eq "143" ]
     exit 0
     exit 1

This is testing for an infinite loop in one of our internal passes that 
were integrated into GCC47. timeout.sh returns 143 code if the 
application times out (in this case timeout is 2 seconds).

The csmith file that I was minimizing is attached.

Let me know if I can help you further.
