[971016] Bug in -fpic code generation on PowerPC?

[Elliot Lee <sopwith at cuc dot edu>]

This is in the latest libc snapshot; 

gcc vfscanf.c -c -O2 -Wall -Winline -Wno-parentheses -Wstrict-prototypes -Wwrite-strings -g  -fpic -fno-common   -I.  -I.. -I../include -I../libio  -I../sysdeps/powerpc/elf -I../crypt/sysdeps/unix -I../linuxthreads/sysdeps/unix/sysv/linux -I../linuxthread

vfscanf.c: In function `_IO_vfscanf':
vfscanf.c:1167: internal error--unrecognizable insn:

        (unspec[

                (mem:SI (plus:SI (reg:SI 31 r31)
                        (const_int 128)))
            ]  8)) -1 (nil)
    (nil))
gcc: Internal compiler error: program cc1 got fatal signal 6
make: *** [vfscanf.os] Error 1

If I compile it with -fPIC instead of -fpic, or without any pic flags at
all, it compiles fine. That leads me to think it's the -fpic stuff...

Anything more I can help with to get this fixed, let me know,
