Is this the same as the code in the last snapshot?  I'm still have
very strange behavior on my Ultra5, and I think it's a bug in rtld.

I originally ended up down this path when I noticed that the configure
script for GNU make was hanging; I determined that by removing -lintl
from the command line, things would proceed normally.  Then I went
over to gettext, and ran *its* regression tests, and found that things
were no better over there.  Since gettext uses libtool, I then backed
up to libtool itself and found the tests failing.

I made a trivial shared library the non-libtool way, and suspect that
RPATH processing is broken.  Watch:

wollman@tsornin(66)$ sh demo.sh
cc -O -o baz.o -c baz.c
cc -O -o libbaz.o -c libbaz.c
cc -O -fPIC -o libbaz.So -c libbaz.c
ar cru libbaz.a libbaz.o
ranlib libbaz.a
cc -static -o baz.static baz.o -L. -lbaz
./baz.static
cc -shared -o libbaz.so.1 -Wl,-soname -Wl,libbaz.so.1
ln -s libbaz.so.1 libbaz.so
cc -o baz.shared baz.o -L. -Wl,-rpath -Wl,/usr/home/wollman/test -lbaz
Next command will hang...
./baz.shared
^C

Here is a shar file with the trivial programs and the test script:
