That bug summary is not informative; it communicates that there was a MOZ_CRASH somewhere in an ASan build (segfault on address 1), on the main thread of some process (T0), and nothing else. The other parts of the message are essentially random numbers. In particular, the assertion failure could have been anywhere in the entire codebase.

The log, however, is more informative:

#0 0x7f78023c72fe in mozilla::ipc::MessageChannel::Clear() /builds/worker/workspace/build/src/ipc/glue/MessageChannel.cpp:786:9
#1 0x7f78023c5e16 in mozilla::ipc::MessageChannel::~MessageChannel() /builds/worker/workspace/build/src/ipc/glue/MessageChannel.cpp:650:3
#2 0x7f78023ff9c2 in mozilla::ipc::IToplevelProtocol::~IToplevelProtocol() /builds/worker/workspace/build/src/ipc/glue/ProtocolUtils.h:392:32
#3 0x7f7806efbeed in mozilla::gmp::GMPContentParent::~GMPContentParent() /builds/worker/workspace/build/src/dom/media/gmp/GMPContentParent.cpp:35:39

This is another MessageChannel destroyed without being closed assertion failure.
