Subject: Shutdown libevent _after_ the subsystems.
X-Git-Tag: tor-0.4.1.2-alpha~22^2~1
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=ba9b0319b00692038e5d4aa2eff7cf5d6947e659;p=thirdparty%2Ftor.git

Shutdown libevent _after_ the subsystems.

This is necessary since shutting down libevent frees some pointer
that the subsystems want to free themselves. A longer term solution
will be to turn the evloop module into a subsystem itself, but for
now it is best to do the minimal fix.

Fixes bug 30629; bugfix on 0.4.1.1-alpha.
