[asterisk-bugs] [JIRA] (ASTERISK-27210) Getting segfault in res_pjsip.so and libasteriskpj.so.2

[Richard Mudgett (JIRA)]

Richard Mudgett commented on ASTERISK-27210:
--------------------------------------------

Sigh.  The install_prereq script is a useful user contributed helper script.  It is a very simple script which simply installs needed packages.  It does not know nor care which version your system is going to install from packages.  The package maintainers for your distribution may even have backported some of the critical fixes to libsrtp for their "older" version of libsrtp.  If your system actually doesn't have a libsrtp package installed, the script can get an unpackaged version when you use the install-unpackaged option.  The unpackaged version the script installs was updated to 2.0 early last month by a community member.

> After investigating the circumstances during that timespan, i saw no behaviour out of the ordinary, and no changes has been made in the last months, and this has never occurred.
> Sadly, this is running in our production system, where we have debug turned off, so i can not provide a backtrace, but was just hoping maybe someone has seen similar before or can pinpoint us the the right direction for collecting more information so we can debug this further.
