FW: gfortran says to submit bug report

[Joe Koski <jkoski11 at comcast dot net>]

While attempting to compile the NIST FDS4 code (f90 based) I get the
following error and a request to submit a bug report:

jakoski$ gfortran -c -O3 -ffixed-form -fno-underscoring mods.f
mods.f: In function 'lpcoef':
mods.f:5099: error: unrecognizable insn:
(insn 613 612 614 22 (set (reg:DF 729)
        (subreg:DF (mem/s:DC (plus:SI (reg/f:SI 114 virtual-stack-vars)
                    (const_int 56112 [0xdb30])) [1413 equiv.1.cm+32 S16
A64]) 8)) -1 (nil)
    (nil))
mods.f:5099: internal compiler error: in extract_insn, at recog.c:2082
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

The compiler that I am using (and can get) is:

Joe-Koskis-Computer:~/Fortran_Compiles/fds_test_compile_gfortran/compiler
error jakoski$ gfortran -v
Using built-in specs.
Target: powerpc-apple-darwin7.9.0
Configured with: ../gcc/configure --enable-languages=c++,f95
Thread model: posix
gcc version 4.1.0 20050517 (experimental)

I'm running on a dual processor G5 Mac under OS X 10.3.9 with Xcode 1.5
installed. A tar of the mods.f file is attached, and the error can be
reproduced by entering

  gfortran -c -O3 -ffixed-form -fno-underscoring mods.f

The source code and make file (for xlf Fortran) are available as downloads
from

http://fire.nist.gov/fds/

Hope this helps your efforts. Let me know if you need more info. If this is
fixed in CVS, just let me know and I'll try gfortran again in a few months.

Sorry for e-mailing, but I tried bugzilla, and find it totally confusing,
especially the "triplets."
