Thank you, Volker and JP, for excellent instructions on #13864 Unfortunately(?) module.py now completes successfully for me. I haven't been able to nudge it into giving the "import segfault" we were seeing before. No surprise if pydebug changes the memory layout of objects. That issue is obviously a delicate memory corruption.
I am getting lots of "visit_decref: Assertion `gc->gc.gc_refs != 0'". If I go up the stack a little and see on what "op" the refcount fails (in gdb, do something like:) (gdb) p PyString_AsString(PyObject_Repr(op)) I saw that BTree from ZODB was implied every time. Indeed, this bug report: https://bugs.launchpad.net/zodb/+bug/641481 seems to indicate was a problem with zodb3-3.7.0 we're using with python 2.7. This supposedly is fixed in the current ZODB3-3.10.5. Installing that seems to have worked for me, so probably just dropping the new source into the spkg provides a valid new package.
