There's an intermittent crash I've been having with this project. In short, it's possible that `ops_secure` in `otr_ops.c` is called with `coi` defined on line 133 as `NULL`. Please see my attached backtrace and let me know if there's anything else I can give you to help. ```gdb (gdb) thread apply all bt Thread 3 (Thread 0x7fb3c53bc700 (LWP 62268)): #0 0x00007fb3c8720aff in __GI___poll (fds=0x55562c692210, nfds=2, timeout=-1) at ../sysdeps/unix/sysv/linux/poll.c:29 #1 0x00007fb3c931936e in () at /lib/x86_64-linux-gnu/libglib-2.0.so.0 #2 0x00007fb3c93196f3 in g_main_loop_run () at /lib/x86_64-linux-gnu/libglib-2.0.so.0 #3 0x00007fb3c956ef8a in () at /lib/x86_64-linux-gnu/libgio-2.0.so.0 #4 0x00007fb3c9342ad1 in () at /lib/x86_64-linux-gnu/libglib-2.0.so.0 #5 0x00007fb3c8806609 in start_thread (arg=<optimized out>) at pthread_create.c:477 #6 0x00007fb3c872d293 in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:95 Thread 2 (Thread 0x7fb3c5bbd700 (LWP 62267)): #0 0x00007fb3c8720aff in __GI___poll (fds=0x55562c67a730, nfds=1, timeout=-1) at ../sysdeps/unix/sysv/linux/poll.c:29 #1 0x00007fb3c931936e in () at /lib/x86_64-linux-gnu/libglib-2.0.so.0 #2 0x00007fb3c93194a3 in g_main_context_iteration () at /lib/x86_64-linux-gnu/libglib-2.0.so.0 #3 0x00007fb3c93194f1 in () at /lib/x86_64-linux-gnu/libglib-2.0.so.0 #4 0x00007fb3c9342ad1 in () at /lib/x86_64-linux-gnu/libglib-2.0.so.0 #5 0x00007fb3c8806609 in start_thread (arg=<optimized out>) at pthread_create.c:477 #6 0x00007fb3c872d293 in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:95 Thread 1 (Thread 0x7fb3c75b2a80 (LWP 62263)): #0 0x00007fb3c5c74ded in ops_secure (opdata=0x7fffff685780, context=0x55562ba8ce40) at src/otr_ops.c:137 #1 0x00007fb3c5bc8ca7 in () at /lib/x86_64-linux-gnu/libotr.so.5 #2 0x00007fb3c5bcec51 in otrl_auth_handle_signature () at /lib/x86_64-linux-gnu/libotr.so.5 #3 0x00007fb3c5bcaf62 in otrl_message_receiving () at /lib/x86_64-linux-gnu/libotr.so.5 #4 0x00007fb3c5c76cf5 in otr_receive (ircctx=0x7fffff685780, msg=0x55562ba44716 "PRIVMSG redcircle :?OTR|1443c377|68d09577,00002,00002,tlIrb/m4px/rNOqw0Xw8I4juyDHSKVohqI7OQD9SW/qaqDkf4GvpGYFIx2j9kCodtOTDRwGnbZIeGRk2/vSS5UhynpI3DSxMTjjNHIkomzwvlPPxJDhmM0ABL8i12zYyxfR+anLXkphR6XimJH"..., from=0x7fffff685790 "xxxx__") at src/otr_util.c:679 #5 0x00007fb3c5c77d8b in hook_privmsg (word=0x7fffff6859c0, word_eol=0x7fffff685ad0, userdata=0x0) at src/hexchat_otr.c:245 #6 0x000055562affb9b3 in plugin_hook_run (sess=0x55562c77aa70, name=0x55562c73bab7 "PRIVMSG", word=0x7fffff6859c0, word_eol=0x7fffff685ad0, attrs=0x7fffff685940, type=6) at ../src/common/plugin.c:569 #7 0x000055562affbba6 in plugin_emit_server (sess=0x55562c77aa70, name=0x55562c73bab7 "PRIVMSG", word=0x7fffff6859c0, word_eol=0x7fffff685ad0, server_time=1626492726) at ../src/common/plugin.c:640 #8 0x000055562b01534b in irc_inline (serv=0x55562ba5c710, buf=0x55562ba446ef ":[email protected] PRIVMSG redcircle :?OTR|1443c377|68d09577,00002,00002,tlIrb/m4px/rNOqw0Xw8I4juyDHSKVohqI7OQD9SW/qaqDkf4GvpGYFIx2j9kCodtOTDRwGnbZIeGRk2/vSS5UhynpI3DSxMTjjNHIkomzw"..., len=436) at ../src/common/proto-irc.c:1578 #9 0x000055562b00098b in server_inline (serv=0x55562ba5c710, line=0x55562ba446d0 "@time=2021-07-17T03:32:06.588Z", len=436) at ../src/common/server.c:291 #10 0x000055562b000c03 in server_read (source=0x55562c64de80, condition=G_IO_IN, serv=0x55562ba5c710) at ../src/common/server.c:355 #11 0x00007fb3c931904e in g_main_context_dispatch () at /lib/x86_64-linux-gnu/libglib-2.0.so.0 #12 0x00007fb3c9319400 in () at /lib/x86_64-linux-gnu/libglib-2.0.so.0 #13 0x00007fb3c93196f3 in g_main_loop_run () at /lib/x86_64-linux-gnu/libglib-2.0.so.0 #14 0x00007fb3c8fa2092 in gtk_main () at /lib/x86_64-linux-gnu/libgtk-x11-2.0.so.0 #15 0x000055562af95358 in fe_main () at ../src/fe-gtk/fe-gtk.c:347 #16 0x000055562afe5759 in main (argc=1, argv=0x7fffff686f48) at ../src/common/hexchat.c:1141 (gdb) frame 0 #0 0x00007fb3c5c74ded in ops_secure (opdata=0x7fffff685780, context=0x55562ba8ce40) at src/otr_ops.c:137 137 otr_notice (coi->ircctx, (gdb) l 132 { 133 struct co_info *coi = context->app_data; 134 char *trust = context->active_fingerprint->trust ?: ""; 135 char ownfp[45], peerfp[45]; 136 137 otr_notice (coi->ircctx, 138 context->username, TXT_OPS_SEC); 139 if (*trust != '\0') 140 return; 141 (gdb) p coi $1 = (struct co_info *) 0x0 ```
