We've seen a few of these over the last couple days with an empty minidump. Maybe OOM-related? https://tbpl.mozilla.org/php/getParsedLog.php?id=32225929&tree=Mozilla-Inbound Android 4.0 Panda mozilla-inbound opt test mochitest-4 on 2013-12-19 09:15:07 PST for push 1f44c2efcd35 slave: panda-0851 09:30:04 INFO - 600 INFO TEST-PASS | /tests/content/media/webaudio/test/test_mediaDecoding.html | Correct sample rate 09:30:04 INFO - 601 INFO TEST-PASS | /tests/content/media/webaudio/test/test_mediaDecoding.html | Found 0 different samples, maxDifference: 0, first bad index: -1 with source offset 0 and destination offset 0 09:30:04 INFO - 602 INFO TEST-PASS | /tests/content/media/webaudio/test/test_mediaDecoding.html | Found 0 different samples, maxDifference: 0, first bad index: -1 with source offset 0 and destination offset 0 09:30:04 INFO - 603 INFO TEST-PASS | /tests/content/media/webaudio/test/test_mediaDecoding.html | Correct duration 09:30:04 INFO - 604 INFO TEST-PASS | /tests/content/media/webaudio/test/test_mediaDecoding.html | Correct length - got 51897, expected about 51896.598639455784 09:30:04 INFO - 605 INFO TEST-PASS | /tests/content/media/webaudio/test/test_mediaDecoding.html | Expect buffer not silent 09:30:04 INFO - 606 INFO TEST-PASS | /tests/content/media/webaudio/test/test_mediaDecoding.html | Found 0 different samples, maxDifference: 0, first bad index: -1 with source offset 0 and destination offset 0 09:30:04 INFO - 607 INFO TEST-PASS | /tests/content/media/webaudio/test/test_mediaDecoding.html | Found 0 different samples, maxDifference: 0, first bad index: -1 with source offset 0 and destination offset 0 09:30:04 INFO - 608 INFO TEST-INFO | MEMORY STAT vsize after test: 812777472 09:30:04 INFO - 609 INFO TEST-INFO | MEMORY STAT residentFast after test: 186998784 09:30:04 INFO - 610 INFO TEST-INFO | MEMORY STAT heapAllocated after test: 41959424 09:30:04 INFO - 611 ERROR TEST-UNEXPECTED-FAIL | /tests/content/media/webaudio/test/test_mediaDecoding.html | This test left crash dumps behind, but we weren't expecting it to! 09:30:04 INFO - 612 INFO TEST-INFO | Found unexpected crash dump file /mnt/sdcard/tests/profile/minidumps/5de8827d-f522-c691-4b38c314-70c4fafc.dmp. 09:30:04 INFO - 613 INFO TEST-INFO | Found unexpected crash dump file /mnt/sdcard/tests/profile/minidumps/5de8827d-f522-c691-4b38c314-70c4fafc.extra.

The logcat from comment 0 is not very helpful: 09:35:16 INFO - 12-19 09:34:39.898 I/ActivityManager( 1402): Process org.mozilla.fennec (pid 2226) has died. It looks like we were in the middle of shutdown (the tests had finished successfully) when we somehow crashed, so maybe we were not in a good state to write a dump?
Although actually there's a: 09:35:16 INFO - 12-19 09:34:39.750 D/GeckoAppShell( 2226): Killing via System.exit() ...so I have no idea what's going on there.
