And Roland won the price again! All Hurd servers and user space programs
which I tried that link to Hurd libraries, like msgport and rpctrace, fail
with this invocation type.
dynamically linked programs fail with:
/hurd/hello: error while loading shared libraries: /hurd/hello: cannot open
shared object file: No such file or directory
statically linked programs fail with:
Killed
A backtrace for the latter is here:
