This bug comes to life again during compilation of llvm-gcc-4.2! Sorry.

llvm::RegScavenger::forward(): Assertion `(isReserved(Reg) || isUnused(Reg) ||
IsImpDef || isImplicitlyDefined(Reg) || isLiveInButUnusedBefore(Reg, MI, MBB,
TRI, MRI)) && "Re-defining a live register!"' failed.
../../../../src/llvm-gcc-4.2/gcc/crtstuff.c:382: internal compiler error:

I'm attaching the bitcode - called crtbegin.bc.
