Hi all,

Our binary runs into the following core dump issue on AIX 7.3 (7300-03-00-2446)
This does not happens instantly but after hours some times even 1 day. We built libzmq 4.3.5 along with libsodium on AIX 7.2
with the following options:

./configure PKG_CONFIG_PATH=/wokrdir/libsodium/lib/pkgconfig/ --with-poller=poll --enable-shared=yes --enable-static=no MAKE="gmake" --disable-perf --with-aix-soname=aix --prefix=/workdir/zmq_4_3_5 --with-libsodium=yes

Now if swap the options of --with--poller=auto the build for libzmq fails:

The result is the same with IBM, gcc compiler.
