g77 bug?

[Jean D. Breshears]

Hello, i believe that i have found some kind of bug in g77 today while
attempting to compile a program. The same program would compile with
egcs 1.2 and on IRIX f77 but crashes with gcc 2.95.2. I don't know
enough to figure the cause of the bug, but i thought i would report my
results.
Anyway, my command line reports:

<root@xenophon prog> g77 -v --save-temps -c -w -O structur.f
g77 version 2.95.2 19991024 (release) (from FSF-g77 version 0.5.25
19991024 (release))
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.95.2/specs
gcc version 2.95.2 19991024 (release)
 /usr/lib/gcc-lib/i386-redhat-linux/2.95.2/f771 structur.f -quiet
-dumpbase structur.f -O -w -version -fversion -o structur.s
GNU F77 version 2.95.2 19991024 (release) (i386-redhat-linux) compiled
by GNU C version 2.95.2 19991024 (release).
GNU Fortran Front End version 0.5.25 19991024 (release)
../../../gcc/f/stw.c:423: failed assertion `b->uses_ != 0'
g77: Internal compiler error: program f771 got fatal signal 6


I have also attached the prepocessed output file 'structur.s' as per
your reporting page.
Thanks and hope this helps. GCC/G77 has always worked well for me in the
past.
Regards,
JD
