I'll attempt to remove the confusion:

The attached code to reproduce this bug (PR#200) *used to* reproduce the problem
when my proposed fix for PR#199 was applied to llvm-gcc.

However, I never committed the proposed fix for PR#199 because it miscompiled
programs.  Instead, I added an assertion that causes gcc to abort.  This will
stay there until a proper fix is available.

The llvm-gcc code pertaining to this bug was still incorrect and could have
caused other programs to crash llvm-gcc.  I commited a cleaned-up version of the
fix I proposed here (gcc-3.4/gcc/llvm-expand.c, revision 1.2) and tested it
before adding the assertion for PR#199.

The problem, then, is that I don't have a way to reproduce this bug in our
official llvm-gcc sources.

Since I'm pretty sure PR#200 is fixed, I'll close this bug as there's nothing
more to be done for it.
