C++ AWS SDK built for Android crashes with no meaningfull log

[BrunoFigRaymarine]

Hello,

I am building and using the SDK on Android and if I build it for Debug it works fine, however when I build it for Release it keeps crashing as soon as I send a request.

Here is the stackstrace

My code works perfectly fine if I build Debug.

Any hints on what to try to debug and fix this issue?

This is how I am compiling it

What platform are you building this on?
What version on this sdk are you using?

I'm going to try to reproduce this on a docker container.
Things that might help you debug/fix this issue:

• try building in a clean directory
• https://github.com/aws/aws-sdk-cpp/blob/main/tools/android-build/build_and_test_android.py
• https://github.com/aws/aws-sdk-cpp?tab=readme-ov-file#building-for-android

Thanks for the Reply. I am building this for Android armeabi-v7a and arm64 . I do build in a clean directory. If I build for Debug I found out it works. If I build for Release it either Hangs or Crashes :(

Have been using latest master.

I have also tried:

• Implementing my own ThreadPool and se it on Executor
• Use different OPENSSL, LIBZ and CRYPTO than the ones built by the SDK
• Use the S3CrtClient instead

All of these have the same result for me :( This is running in a QT application on andorid
