Crash with python 3.6 on Mac OS X 10.12 (Sierra)

[Hugues Talbot <hugues.talbot@…>]

Hello All,

I'm experiencing a crash in boost-python with python 3.6 on OS X.

I'm trying to wrap the open-source image processing library pink (www.pinkhq.com). This has been working well for some time with python 2.7 (on OS X, but also Linux and Windows), but I'd like to move to python 3.x

I've successfully wrapped this library with python 3.6 on Linux, but it crashes on OS X :

This crash seems to indicate the problem is in libboost_python ; Unfortunately I cannot do much more at this point because gdb is not allowing me to set breakpoints and I don't know why.

However, does this ring a bell with anyone ? can anyone offer suggestions ? All the best.
