Ideally we would get that tombstone: /data/tombstones/tombstone_03

We publish symbols for libskyshell.so these days, in the same GCS bucket as the jar, etc is published.

@jason-simmons may be able to help you debug. We need to get the C++ stacktrace (part of which you've posted), symbolicate it and then debug from there. Alternatively we could run inside a debugger on the device, but that's likely not necessary.

Is this on a JIT (debug) build or using precompiled code (profile and release)?

Closing as ancient.
