Hi,
It seems that sq_sig_all is not properly set when creating the QP or
when querying it. The following programs creates a bunch of QP with
sq_sig_all set to 0 and then queries them. Often sq_sig_all is returned
to be 1.
I tested some other returned values and they seem correct.
I didn't see

Hello,
in write_bw_postlist.c, my_dest (and possibly rem_dest) must be initialized,
else the remote node may not be able to parse the connection string and the
test will fail to start.
The others test are doing that initialization.
