[lttng-dev] Need help in using lttng - module crashes

[Jérémie Galarneau]

You could also try the latest 2.3.x releases which may already contain a
fix for this issue. However, note that the 2.3.x release is no longer
maintained.

lttng-tools 2.3.2 [1]
lttng-ust 2.3.2 [2]
lttng-modules 2.3.5 [3]

Regards,
Jérémie
