title: App crashing without Tombsone (Fatal signal 11 (SIGSEGV), code 1, fault addr 0x20 in tid 23873)
body: <p>I'm getting the infamous fatal signal 11 crash from a JNI library I am using. However, the crash is not providing a tombstone, only offering these messages:</p>
  
  <pre><code>02-03 21:45:41.857 3080-3080/? E/DEBUG: Failed to find a valid tombstone, default to using tombstone 0.
  02-03 21:45:41.857 3080-3080/? E/DEBUG: failed to open tombstone file '/data/tombstones/tombstone_00': No such file or directory
  02-03 21:45:41.857 3080-3080/? I/DEBUG: Skipping tombstone write, nothing to do.
  </code></pre>
  
  <p>Is there anything else I can use to find out why the crash happens?</p>
