I built SPEC CPU 2K with gcc 4.0 and ran with libgfortran.so in gcc 4.1. I
got
Specinvoke: /export/spec/src/2000/spec/bin/specinvoke -E -d
/export/spec/src/2000/spec/benchspec/CFP2000/172.mgrid/run/00000002 -c 1 -e
compare.err -o compare.out -f compare.cmd
*** Miscompare of mgrid.out, see
/export/spec/src/2000/spec/benchspec/CFP2000/172.mgrid/run/00000002/mgrid.out.mis

Change to libgfortran.so in gcc 4.0 fixed the problem.
I have 2 questions:
1. Is output of FORTRAN in gcc 4.1 binary compatible with gcc 4.0?
2. Should libgfortran.so in gcc 4.1 be backward compatible with
libgfortran.so in gcc 4.0?
