 GCC build triplet: 3.4 20031008

I don't see any place to upload files... here's the gcc -v -save-temps output;
let me know where I should send the source and preprocessed files.

The error persists in gcc 3.4 20031015. I have simplified the required options
to cause the error:

gcc -lm -lrt -DGCCGA -O1 -o almabench -march=pentium4 -fgcse -finline-functions
-fnew-ra almabench.c

Also, I get the same ICE on a C++ program, using slightly different options:

g++ -lrt -o fftbench -march=pentium4 -fno-inline -fnew-ra fftbench.cpp

In both cases, -fnew-ra is involved, as is -march=pentium4.

The above is a different program from the one provided with the initial bug
report. All programs that break are floating-point intensive. I will try to
reduce the size of these programs even more to find specific routines causing
the problem.

Output of -v -temps from the second compile is:
