I committed and pushed some changes a while ago, which I believe fixes
the issue, please get the latest git/snapshot and see how it works for
you!
there are some compile issues with git head
1) url.c "url.c:4932: error: 'struct PureInfo' has no member named 'ip'"
i just renamed ip to primary_ip. maybe you forgot to commit changes in
url.c?
2) connect.c:860: error: 'sa6' undeclared
is inside #ifdef ENABLE_IPV6 i changed to
so i added +struct sockaddr_in6 * const sa6 = (void *)&addr.sa_addr;
Now my test with the easy interface do work, but not the one with the
multi interface.
There the problem persists: the ip info of the reused connection is empty.
