Crash when using the API after calling shutdown()

[jduck]

Version and Platform (required):

• Seems to affect all versions (from 4.2 to 5.0 at least)
• OS: Ubuntu Linux
• OS Version: 24.04
• CPU Architecture: x64

Bug Description:
Binary ninja crashes with evidence of memory corruption:

Steps To Reproduce:

lappy [0] ~/binaryninja » python
Python 3.12.3 (main, Feb  4 2025, 14:48:35) [GCC 13.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import binaryninja
>>> binaryninja.core_version()
'5.0.7182-dev Ultimate'
>>> binaryninja.shutdown()
>>> bv = binaryninja.load("/bin/ls")
double free or corruption (!prev)
Aborted

Expected Behavior:
Not sure... Maybe successfully loads the new binary? Maybe just error about how you shutdown and so shouldn't expect the API to continue working?

Note for me: this is a good test for the unit test here: https://github.com/Vector35/binaryninja-api/blob/dev/rust/tests/initialization.rs

Specifically try and do an operation such as load after shutdown.
