crash in mozilla::ipc::Message
Channel::On Maybe Dequeue One()
This bug was filed from the Socorro interface and is report bp-00a2ecd0-3c18-44f6-8aca-536f62131006. ============================================================= This crash began happening on 20130929030202 Nightly and has climbed up to #8 on crash list. nothing of note in correlations or URLs
This may just be a changed signature of RPCChannel being renamed to MessageChannel, *but* we fixed the majority of that crash in bug 800347. Can you check for matching signatures before, and also provide a regression range if this is a new crash? There have been several IPC changes that landed recently, IIRC.
This signature is currently #4 on Nightly. Investigating further, I don't think this morphed from bug 800347 - crash in mozilla::ipc::RPCChannel::OnMaybeDequeueOne. Tthe fix there and the first appearance of this signature don't match. regression range (based on first appearance of this signature) - http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=2f4397db1830&tochange=8f805d3ef377
Bug 901789 is the clear suspect. dvander can you take of investigating and possibly backing that patch out in the meantime?

It appears that the new MessageChannel::~MessageChannel doesn't call Clear() at all, even though both AsyncChannel and RPCChannel used to. I'm also a little confused about the patch http://hg.mozilla.org/mozilla-central/rev/9cc90a4b6475 because it looks like AsyncChannel.cpp still exists, but is not built.
Yeah I'm not sure how that happened. I was very careful to include your changes in the final patch. Something must have gone wrong in between. Easy to fix though.
topcrash is being replaced by more precise keywords per https://bugzilla.mozilla.org/show_bug.cgi?id=927557#c3
