https://hg.mozilla.org/try/file/fad4e7d9ecf6c84f2515fe651461bc6e76d9ad54/dom/media/gtest/TestVideoFrameContainer.cpp contains a simple gtest that puts a PlanarYCbCrImage in an ImageContainer and runs pending events.

This crashes on Android only. The crash does not occur with ImageContainer::SYNCHRONOUS. It also does not occur if the PlanarYCbCrImage has no data set.

The backtrace has no symbol names. When disabling stripping of the gtest libxul.so and extracting target.gtest.tests.tar.gz, /opt/android-ndk/ndk-stack -sym gtest/gtest_bin/gtest/ < stack-without-symbols produces a trace with some symbols, but I don't know whether to believe them.
