OK, here's what I did on an IA-64 system; it's pretty basic.
gcc-mainline is a symbolic link to the CVS gcc tree, last updated
Wed Oct 10 19:07:42 UTC 2001.

ld -v:
   GNU ld version 2.11.92.0.5 20011005.
gcc -v (partial):
   gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-96).
uname -a:
   Linux elm3a81 2.4.7-2smp #1 SMP Tue Aug 14 04:31:14 EDT 2001 ia64 unknown

mkdir gcc-obj
cd gcc-obj
../gcc-mainline/configure --prefix=/home/janis/gnu/tools \
  --enable-languages="c,c++" > configure.log 2>&1
make > make.log 2>&1

I've got two object files that will cause the same failure with the command
"ld -G stl-inst.o string-inst.o -o libx.so", with either a native ia64-linux
linker or a cross linker on i686-pc-linux-gnu (both 2.11.92.0.5).  Let me
know if you'd like those files.
