Duane Griffin added the comment:
I cannot reproduce the segfaults for the first four issues however valgrind
still reports problems for all but the second. The fifth (last) one still
segfaults.
I have a patch for the fifth issue. The other remaining issues are all
reporting the same invalid read at exit. I'm not sure whether that is the same
issue reported here or something else that they all trigger:
Invalid read of size 8
at 0x43C5FA: delete_garbage (gcmodule.c:868)
by 0x43C5FA: collect (gcmodule.c:1019)
by 0x43D2F0: _PyGC_CollectNoFail (gcmodule.c:1623)
