I've managed to complete the build of firefox52 with crash debug info
(PKG_OPTIONS.firefox+=debug-info) and started it with a clean user
setup ($HOME empty except for standard skel files).

Result:

firefox52

Core was generated by `firefox52'.
Program terminated with signal SIGBUS, Bus error.

(gdb) 

The line referred to in the crash is:
  NS_RUNTIMEABORT("Aborting on channel error.");

context:

void
MessageChannel::OnChannelErrorFromLink()
{
    AssertLinkThread();
    mMonitor->AssertCurrentThreadOwns();

    IPC_LOG("OnChannelErrorFromLink");

    if (InterruptStackDepth() > 0)
        NotifyWorkerThread();

    if (AwaitingSyncReply() || AwaitingIncomingMessage())
        NotifyWorkerThread();

    if (ChannelClosing != mChannelState) {
        if (mAbortOnError) {
            NS_RUNTIMEABORT("Aborting on channel error.");
        }
        mChannelState = ChannelError;
        mMonitor->Notify();
    }

    PostErrorNotifyTask();
}


So that is an intentional shutdown due to an IPC error caused (presumably)
by the actual underlying error. Looks like firefox52 is not very debug
friendly to people not familiar with it.

That's as far as I can get, giving up here.

Kind regards,
           Alex.
