[Bug runtime/10772] New: Errors when using --server flag of stap-client

["rgrunber at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

Start a server using stap-start-server, then run stap-find-servers to find the
host, ip and port.

Run the following commands :

stap-client --unprivileged --server=ip -e 'probe begin {printf ("hello world\n")
exit()}'

stap-client --unprivileged --server=ip:port -e 'probe begin {printf ("hello
world\n") exit()}'

stap-client --unprivileged --server=host -e 'probe begin {printf ("hello
world\n") exit()}'

stap-client --unprivileged --server=host:port -e 'probe begin {printf ("hello
world\n") exit()}'


I had the following output :


rgrunber@tommycat:systemtap$ 
rgrunber@tommycat:systemtap$ stap-find-servers

-e 'probe begin {printf ("hello world\n") exit()}'
hello world
rgrunber@tommycat:systemtap$ 
rgrunber@tommycat:systemtap$ 

Note that supplying --server=host and --server=ip:port generate an error but
--server=host:port and --server=ip work as expected.
