[New-bugs-announce] [issue34884] Python loads incorrect libraries

Tim Hutt report at bugs.python.org
Wed Oct 3 06:34:36 EDT 2018 

New submission from Tim Hutt <tdhutt at gmail.com>:

See this issue: https://bugs.llvm.org/show_bug.cgi?id=38974

Basically if you have a copy of Python 2 installed on OSX from brew (as well as the system Python 2), then when you run lldb (which links to the system Python 2), at some point Python gets confused and starts loading libraries from the brew version of Python 2.

To reproduce:

1. Install Xcode.
2. `brew install python2`
3. Create some executable.
4. `lldb a.out`

The output is:

(lldb) target create "a.out"
Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "/usr/local/Cellar/python at 2/2.7.15_1/Frameworks/Python.framework/Versions/2.7/lib/python2.7/copy.py", line 52, in <module>
    import weakref
  File "/usr/local/Cellar/python at 2/2.7.15_1/Frameworks/Python.framework/Versions/2.7/lib/python2.7/weakref.py", line 14, in <module>
    from _weakref import (
ImportError: cannot import name _remove_dead_weakref

You can also run it like this:

$ cp /usr/bin/lldb ~/lldb   # Work around SIP
$ DYLD_PRINT_LIBRARIES=1 ./lldb a.out

And it gives the output below (note lines marked with *******).
