State-Changed-Why:
    I was unable to reproduce this with the gcc 3.0.x branch
    and the gcc 3.1 development trunk.
    
    gcc.gnu.org does not have 6 month old snapshots, so I
    checked out a 6 month old copy using the tag
    gcc_ss_20010320.  I reproduced the problem with this
    source tree.  There is an infinite recusion in canon_rtx
    due to a code rewrite done by the AUTO_INC_DEC code in
    flow.c.  This is the same problem addressed in PR 3783.
    It was fixed by the alias.c/flow.c patch I checked in
    last week.  See PR 3783 for more info.
