NET 9.0 Android Console App SIGSEGV Crash

[truboxl]

Description

Publish a console app using linux-bionic-arm64 and running on the phone causes Segmentation Fault.
I am not able to observe this issue on NET 8.0 SDK but on NET 9.0 SDK.

Reproduction Steps

1. dotnet new console -o hello
2. cd hello
3. dotnet publish -r linux-bionic-arm64 --self-contained -f net9.0
4. Copy all the contents in bin folder to phone
5. Run bin/Release/net9.0/linux-bionic-arm64/hello on the phone using adb or Termux app
6. Observe crash

Expected behavior

Should not crash. Prints Hello, World!

Actual behavior

Prints Segmentation Fault and crash. Attach logcat.txt for inspection.

Regression?

Works on NET 8.0 (8.0.11).

From your logcat, it looks like the libraries aren't readable:

I believe that is expected from an unrooted Android phone. I will try to find an emulator set-up and reproduce the issue to recapture logs if possible.
