Christoph Gohlke's Shapely‑1.5.9‑cp27‑none‑win_amd64.whl includes a version of geos_c.dll that has the VC90 manifest embedded as resource 2, just like python27.dll. The DLL also exports a GEOSFree function, which is what shapely actually uses. That said, the geos.py module still defines a global free() using cdll.msvcrt.free. As far as I can see, it never actually calls it. Otherwise it would surely crash the process due to a heap mismatch. Steve, since you haven't closed this issue, have you considered my suggestion to export _Py_ActivateActCtx and _Py_DeactivateActCtx for use by C extensions such as _ctypes.pyd? These functions are better than manually creating a context from the manifest that's embedded in python27.dll because they use the context that was active when python27.dll was initially loaded. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24429> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
