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?
