I tried with the gcc-4_3-branch from Subversion today, but it doesn't change
things: plain -O2 fails but both -O2 -funroll-loops and -O1 succeed on the test
case.
For the record:
(sid)kmccarty@merulo:~$ ~/gcc-4.3-branch/bin/gfortran -v
Using built-in specs.
Target: ia64-unknown-linux-gnu
Configured with: ./configure --enable-languages=c,fortran
--prefix=/home/kmccarty/gcc-4.3-branch --enable-shared
--with-mpfr=/home/kmccarty/gcc-4.3-branch
Thread model: posix
gcc version 4.3.1 20080521 (prerelease) (GCC)
