I wonder if anyone has any clue as to why androidNative executables don't work. I have a hello world executable that segfaults. Android logcat shows

I'm not experienced in native development, but none of my attempts led anywhere - addr2line gives ??, malloc debugging (here) does nothing. I managed to get a linux core dump and fed it to lldb, but I'm not able to get any information from it.

The same code works perfectly when compiled as a shared library. Any clue on how to dig deeper before filing an issue?
