simpleclient failed and IPv4 networking test .. stuck

[shlomopongartz]

I build from clean with ./buildrump.sh -D -V RUMPUSER_THREADS=fiber -V RUMP_CURLWP=hypercall

and I see this error messages

link simpleclient/simpleclient

ERROR:

However the file ./tests/simpleclient was created, but few lines later I saw that "IPv4 networking test ..." was stuck forever.
