Are there any other logs? For example, a fatal log before it?

This may simply be the OS deciding the process has taken too long. In which case we could register a signal handler listening for SIGABRT following a stop and not bother printing a stack trace. Or it could be a LOG_FATAL somewhere due to some misused API. It is hard to tell from just this.

I see a fatal log from libc.

F/libc    (21438): Pure virtual function called. Are you calling virtual methods from a destructor?

Could it be why the asset pointer being a dangling pointer? If you can't reproduce, I will try to investigate it further when I have time.

This is almost 3 years old and much has happened in gomobile since then. I'll close this until a reproducer surfaces.
