On my local development system I just discovered the following:

  • Status changed from New to Feedback
  • Assignee changed from neels to laforge

looking at the code, this can only be a use-after-free (i.e. not a NULL dereference).
laforge, you don't possibly have a way to reproduce? log output? pcap?
The information in this ticket is not sufficient to identify the cause.

My wild guess is that in tch_bridge, the one call_leg or rtp_stream that is to be bridged is already deallocated,
but for some reason the pointer to it still sticks around??
Maybe there is a corner case where an RTP stream setup failure doesn't cascade into a proper cleanup?

Unfortunately none of the above is available. It happened once while working on OsmoBSC with E1 BTS (BSC/RAN on a different machine). But the latter shouldn't matter at all. I don't usually pre-emptyively run pcap traces on systems that are not part of my work / test (i.e. if I develop something on the RAN, on a different machien, I don't take pcap files on the remote CN).

The problem has not re-occurred since.

The log file output ahead of the crash(Also not very verbose, as the MSC was not part of my development work):

There are no other log file entries of osmo-msc anywhere near that timestamp, the previous messages are from 19 hours earlier, so I doubt any previous state has impacted this.
