I built lldb with `LLDB_ENABLE_PYTHON_LIMITED_API` against Python 3.14 from python.org. I then tried to import it from Python 3.12 installed with Homebrew. That causes a crash in `_PyObject_Malloc` during initialization:
```
* thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x10)
frame #0: 0x000000010879560c Python`_PyObject_Malloc + 52
Python`_PyObject_Malloc:
-> 0x10879560c <+52>: ldr x8, [x8, #0x10]
0x108795610 <+56>: ldr x19, [x8, #0x2aa8]
0x108795614 <+60>: sub x8, x1, #0x201
0x108795618 <+64>: cmn x8, #0x200
