poll-tests: Pipe test crashes wineserver

[Simon Josefsson]

Running this

address@hidden:~/src/gnulib master$ rm -rf m;gnulib-tool --create-testdir 
--with-tests --dir m poll; cd m; ./configure --host=i586-mingw32msvc 
--build=i686-pc-linux-gnu; make check; cd ..

I get this output:

Unconnected socket test... passed
Connected sockets test... passed
General socket test with fork... passed
Pipe test... wineserver crashed, please enable coredumps (ulimit -c unlimited) 
and restart.
PASS: test-poll.exe

When the self-test is ran inside gsasl, test-poll.exe hangs instead, I'm
not sure why.

Can anyone reproduce this?

(To get the first command to work, you'll likely need the patch I posted
about test-poll vs ioctl earlier.)
