Package: libboost-numpy1.67.0
Version: 1.67.0-13
Severity: important
Tags: upstream
Dear Maintainer,
Python modules built with libboost-numpy cannot be imported in python3, because
they fail to initialize. The following
module can be used to reproduce the behaviour
$ cat segfault.cpp
#include <boost/python.hpp>
#include <boost/python/numpy.hpp>
BOOST_PYTHON_MODULE(segfault) {
Py_Initialize();
boost::python::numpy::initialize();
}
I compiled this and linked against python3
$ g++ -fPIC -shared -I/usr/include/python3.7m -lboost_numpy37 -lboost_python37
segfault.cpp -o segfault.cpython-37m-
x86_64-linux-gnu.so
The result of importing this module is
$ python3 -c "import segfault"
RuntimeError: FATAL: module compiled as little endian, but detected different
endianness at runtime
ImportError: numpy.core._multiarray_umath failed to import
Traceback (most recent call last):
File "<string>", line 1, in <module>
SystemError: initialization of segfault raised unreported exception
The issue only affects the python3 version, python2 works as expected.
This issue was repored upstream here:
https://github.com/boostorg/python/issues/214
There is already a fix applied upstream:
https://github.com/boostorg/python/pull/218/commits/0fce0e589353d772ceda4d493b147138406b22fd
It is included in boost release 1.68, but would need a backport for buster.
Would it be possible to include the patch into Debian stable?
Thank you in advance
Moritz
