Is that the only srtp_diagnostic_patch message in the log? I was kinda hoping you'd post a log file containing everything from the start of the run to the crash :P

EDIT:  Also, the gdb.txt you posted most recently appears to not be using the patch. The backtrace.txt is however, so I'm guessing it's just an old core dump or something? It doesn't really matter since what I'm trying to look at are log messages anyway.

I'm a little bothered that the log messages might be being deferred before the crash occurs, so I'm going to update the patch real quick to include a sleep before what appears to be the offending line.

> A call from snom320 in SRTP mode to echo test or to another phone *NOT* using SRTP is OK. Now we installed PhonerLite softphone with TLS/SRTP stuf and test with echo test: everything is OK too.
> Now PhonerLite calls the snom: asterisk coredump after 3~5 seconds and we are NOT able to make anymore SRTP calls after this, they all crash asterisk. We had this issue with 10.7.0 and 10.8.0
> We have logfiel from strace as well as coredump.
