[tor-dev] Tor crash debug

[Nurmi, Juha]

Hi,

I have been running Tor on tor2web mode[1] and now it has started to crash.

See error on /log
http://nzxj65x32vh2fkhk.onion/pwnzwpknl

To understand the bug I re-installed Tor in Tor2web mode for debbuing:

make clean && CFLAGS="-ggdb3 -O0" LDFLAGS="-ggdb3" ./configure --disab
le-asciidoc --enable-tor2web-mode && make && make install

And running it

gdb tor
(gdb) run

Program received signal SIGSEGV, Segmentation fault.
0x00005555555c02d6 in rend_client_get_random_intro_impl (
   entry=0x5555555bf1bf <rend_client_fetch_v2_desc+114>, strict=0,
warnings=0)
   at src/or/rendclient.c:1353
1353      smartlist_add_all(usable_nodes, entry->parsed->intro_nodes);

Any ideas what is the problem? Is there anything more I could do to debug
this?
