I don't know how to interpret this comment. There are 124 hits of "Lucier"
in gcc-bugs; the report I referred to in my original post,
shows exactly where the bad code is inserted. I just don't know how to
use gdb on cc1 to break precisely when gcse attempts to add this code
to this block to find out *why* it wants to do this.
