[Bug fortran/33006] New: internal compiler error: in simplify_subreg, at simplify-rtx.c:4676

[Bug fortran/33006] New: internal compiler error: in simplify_subreg, at simplify-rtx.c:4676

[michael dot a dot richmond at nasa dot gov]

When I attempt to compile the program listed below I get the following message:

a.f90: In function 'MAIN__':
a.f90:2: internal compiler error: in simplify_subreg, at simplify-rtx.c:4676
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

The conditions were:

1. The August 3 version of gcc and gfortran were used. The problem does not
occur with the July 27 version.
2. It was run on an SGI box under Debian Linux. I have not tested it on other
processors.
3. The program was compiled with the flag "-fdefault-integer-8". It does not
produce the error without this flag.
4. If I replace z = MAX(x,y) with i = MAX(j, k) the problem disappears.

PROGRAM test
z = MAX(x,y)
END PROGRAM test

Yes we know, we are trying to resolve more and more of these
-fdefault-integer-8 bugs.
