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.
