The LAPACK testsuite fails with the following error message with -O3
-march=pentium4 -funroll-loops:

At line 1162 of file schkee.f
Fortran runtime error: Bad integer for item 1 in list input

This is not a gfortran frontend problem because LAPACK passes fine without
optimization.

Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../main/configure --prefix=/home/jerry/gcc/usr
--enable-languages=c,fortran --disable-libmudflap
Thread model: posix
gcc version 4.2.0 20060126 (experimental)

I have not tried 4.1 yet.  This might be considered critical considering the
widespread use of LAPACK.
