[tor-dev] tor's "make test" fails when run on tails

I am trying to execute tor's tests from git (63a90f2) on tails but the socketpair_ersatz test keeps failing

util/socketpair: [forking] OK util/socketpair_ersatz: [forking]

FAIL src/test/test_util.c:4212: assert(0 OP_EQ tor_socketpair_fn(family, SOCK_STREAM, 0, fds)): 0 vs -111 [socketpair_ersatz FAILED] util/max_mem: OK

The failure seems to be in connect(): https://gitweb.torproject.org/tor.git/tree/src/common/compat.c#n1492

armadev said on IRC that he/she could make the tests pass, so I wonder if there might be some specific behavior on tails that prevents the test from passing successfully.

Is there a suggested workaround? Or perhaps is it possible to easily ignore this one test?
