I have been running Tor on tor2web mode and now it has started to crash.

It crashes after few minutes of use. Before that it works normally.

Program received signal SIGSEGV, Segmentation fault.

   at src/or/rendclient.c:1353
1353      smartlist_add_all(usable_nodes, entry->parsed->intro_nodes);

Tor version: Tor 0.2.7.6 (git-605ae665009853bd)

On log: Apr 29 03:52:05.920 [notice] Tor v0.2.7.6 running on Linux with Libevent 2.0.21-stable, OpenSSL 1.0.1f and Zlib 1.2.8. ... Apr 29 03:52:18.000 [notice] Tor has successfully opened a circuit. Looks like client functionality is working. Apr 29 03:52:18.000 [notice] Bootstrapped 100%: Done
