This bug was filed from the Socorro interface and is 
report bp-7ec6db6a-d9c1-446f-88ac-0261f0170618.
=============================================================

Seen while looking at crash stats - crashes started using 20170615030208: http://bit.ly/2tjYZH4. Affects both Firefox and Fennec.


Possible regression range based on Build ID: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=b266a8d8fd595b84a7d6218d7b8c6b7af0b5027c&tochange=035c25bef7b5e4175006e63eff10c61c2eef73f1

1 or 2 Fennec crashes on 54, but no FF crashes showing up in either 54 or 55.

We are likely triggering an assertion prior to the crash:
    MOZ_ASSERT(aContainer->mPrepared);

Would be great to have the log and the crash dump.

Attachment: log of assertion

Indeed it crashes opt and asserts debug with:
Assertion failure: aContainer->mPrepared, at /home/worker/workspace/build/src/gfx/layers/composite/ContainerLayerComposite.cpp:576

mozilla::layers::ContainerRender<T> was last seen in Build 20170706060058
void mozilla::layers::ContainerRender<T> was last seen in Build 20170704100320
