Research direction

The issue names no source file or test. Start by reproducing the listed dotnet publish command on an Android phone and inspect the attached logcat.txt, then compare the net9.0/linux-bionic-arm64 result with the working .NET 8.0 case. Done means the published console app runs without a segmentation fault and prints "Hello, World!".

Description

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).
