Version and Platform (required):
Binary Ninja Version: 4.1.5902 (f2165c5d)
OS: MacOS Sonoma
OS Version: 14.1 (23B2073)
CPU Architecture: M3

Bug Description:
Using Python API to process a large file. The preliminary analysis threw a large number of these errors:

[3695165033425039954:3963300147212102244 Function warn] Skipping analysis for function at 0x281ec0 : Exceeds 'analysis.limits.maxFunctionUpdateCount'. If possible, please report this issue.

The UI throws this error:
[Default] Trying to add a local variable at positive storage offset 4. Please report this issue.

Steps To Reproduce:
May be as simple as loading the binary via the Python API or opening it in the application.

Expected Behavior:
I expected not to be asked to report an error.

Screenshots/Video Recording:
If applicable, please add screenshots/video recording here to help explain your problem.

Binary:
Attached.

Additional Information:
This was compiled natively on a M3 MacBook Pro.

Research direction

Start by loading the attached git-add-armv7l binary through the Python API and the Binary Ninja application, then observe the maxFunctionUpdateCount and positive storage offset errors reported during analysis. The issue is resolved when the binary can be analyzed without those errors or the failure is narrowed to a reproducible analysis case.
