So I just installed llvm-1.4 (on gcc-3.3.4, gentoo i386) without frontends 
and tried to run the tests.  But there is apparently some odd 
bytecode "corruption" going on ...

e.g. here i get: 

    <... traceback ...>
    ExecutionFailed: 1  llc _my_gcd_wrap.o.bc -f -o _my_gcd_wrap.s
    llc: bytecode didn't read correctly

any idea what could be the problem here?
