Do you mind creating an issue here https://github.com/android/ndk/issues  ?

This is not an NDK issue, so that's not the right place :)

We don't test on WSL2 - does it reproduce natively on Linux?

further down below makes it similar to https://groups.google.com/g/android-llvm/c/l0cz8MgvTZI but there was no resolution tin that discussion.

Thanks for your help. I see it's a WSL bug, and some other elf binaries also meet this error as WSL is not perfect to support the elf specification. Any way, I will try to compile ack on Linux.
