[Bug c++/13229] New: Odd combination of optimizations causes ICE in double complex loop

["coyote at coyotegulch dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The following was discovered by my automated Acovea testing facility.

An ICE occurs when compiling the attached C++ file with the following command
line and gcc 3.4 20031126:

g++ -c -O1 -fno-loop-optimize -fgcse -funit-at-a-time gcc-ice1.cpp

This is a very obscure error, given that no one is likely to intentionally
combine the above options. However, it is an ICE, and may be related to other
problems in the compiler.
