This crash occurred while rotationally launching Firefox and Calculator on B2G and randomly closing the pipe_.
Currently I can't provide a testcase due to the nature of the fuzzer. Working on it. Let me know if you need further information.
The "callstack" shows the full session.

Don't put anonymous sockets in the PipeMap because they can collide
This happens because we have two anonymous unconnected channels, in certain race conditions: the process channel for the content process, and the PCompositor channel.
