Public bug reported: I was trying to configure openstack nova-compute service on an Power8 LE guest with ubutu 15.04 ppc64el beta2 installed. But it crash when calling greenlet 'switch' function.
So I re-build the greenlet.so from the source, and found that it still crash when running tests. Here are log, # apt-get source python-greenlet # apt-get build-dep python-greenlet # dpkg-source -x python-greenlet_0.4.5-1ubuntu1.dsc # cd python-greenlet-0.4.5/ # python setup.py build running build running build_ext building 'greenlet' extension creating build creating build/temp.linux-ppc64le-2.7 powerpc64le-linux-gnu-gcc -pthread -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fno-strict-aliasing -D_FORTIFY_SOURCE=2 -g -fstack-protector-strong -Wformat -Werror=format-security -fPIC -I/usr/include/python2.7 -c greenlet.c -o build/temp.linux-ppc64le-2.7/greenlet.o creating build/lib.linux-ppc64le-2.7 powerpc64le-linux-gnu-gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions -Wl,-Bsymbolic-functions -Wl,-z,relro -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -D_FORTIFY_SOURCE=2 -g -fstack-protector-strong -Wformat -Werror=format-security -Wl,-Bsymbolic-functions -Wl,-z,relro -D_FORTIFY_SOURCE=2 -g -fstack-protector-strong -Wformat -Werror=format-security build/temp.linux-ppc64le-2.7/greenlet.o -o build/lib.linux-ppc64le-2.7/greenlet.so # ./run-tests.py running build_ext Linking /root/greenlet/python-greenlet-0.4.5/build/lib.linux-ppc64le-2.7/greenlet.so to /root/greenlet/python-greenlet-0.4.5/greenlet.so python 2.7.9 (64 bit) using greenlet 0.4.5 from /root/greenlet/python-greenlet-0.4.5/greenlet.so test_version (tests.test_version.VersionTests) ... ok test_generator (tests.test_generator.GeneratorTests) ...
