I am currently experiencing the exact same
problem. Did you ever find out what the problem
is?
Any help would be appreciated...

Try this instead:
g++ -fpic -c a.C
g++ -fpic -c b.C
ld -b a.o b.o -o x.sl
This works for me. I've had problems in the past with g(cc/++)'s
-shared
flag on HP-UX. This makes the linker do it.

This is wrong. Your ctors and dtors in the shared library will not work.
The solution for this problem is in the FAQ. It's not hard. The entry
"why can't I build a shared library".

A common trap in building shared C++ libs is that gcc itself (and
libstdc++.a) does not bootstrap PICly by default. You have to tell it
to. Configure as usual, and
make bootstrap CFLAGS=-fPIC CXXFLAGS=-fPIC
Also, pass -fPIC (-fpic?) on the link line as well because, when
linking, g++ (collect2) generates code for the ctors of global objects
to be called properly. This code has to be compiled PICly.
I don't know if this cures all of your problems for the HP, but it
sure helps along the way. I once managed to make a HP shared lib with
gcc 2.7.2.3, and ended up with a weird link line that read as follows,
for whatever reason.
g++ -fPIC -shared <the files> -l<library1> ... \
-Xlinker +I -Xlinker _GLOBAL__DI \
-u __eprintf -u __pure_virtual -u __builtin_delete \
-u __builtin_new -u __builtin_vec_delete -u __builtin_vec_new \
-u __muldi3 -u __udivdi3 -u __umoddi3 -lgcc \
