flaky upon interrupted add-on download

Post by Icekiss »

To reproduce:
1. Start downloading a (bigger) add-on from within wesnoth.
2. Interrupt you internet connection while the download is going on.
3. wait until you get the "remote host disconnected" message
4. click again on "Add-ons"

The first time this (accidently) happened, wesnoth crashed with a memory access violation. I Tried it again to see whether it is reproduceable -> wesnoth hung with full cpu utilization.

OS: Debian unstable
wesnoth version: 1.3.10

No crash here with 1.3.10 or 1.3.10+svn.
It'd be very helpful if you can get a backtrace from that crash.

All right, I'm recompiling wesnoth with '--enable-debug'.
After that I'll see whether I can get gdb to spit the info out (haven't done this before).
This'll take a bit... :P

gdb's command is 'bt' (backtrace, remove the ').

I use ddd for getting a friendly user interface.

Allright, I couldn't get it to compile using the command './configure --with-kde --enable-debug' (during make, the linking failed). I am retrying with only the '--with-kde' switch to see whether my system or my procedure changed (after all, I do have wesnoth running).
Since you are implying that a backtrace would be useful even without the debugging symbols, here it is:

Doesn't look all that usefull to me. But if it helps...

Just finished compiling again using './configure --with-kde' (yes, my machine isn't the fastest, so these things take a bit. :) ). Runs through without errors 8) . However, compiling with './configure --with-kde --enable-debug' aborted with:

Am I using configure incorrectly?
No idea whether this has any bearing on the bug, so unless you need the debug symbols, feel free to ignore it. :)

Since I spotted the sticky "how to generate a backtrace", here is the end of a backtrace gotten with 'gdb wesnoth', and 'run'. (PS: As can already be seen from my first post, it doesn't crash every time, but so often that it is easy to catch (50% maybe))

gdb wesnoth

Can still easily crash 1.3.11 in this way.
In contrast to 1.3.10, I was able to compile it using 'configure --enable-debug'. However, gdb still says it can't find the debugging symbols, and stays uninformative. :(
Guess I will have to try out the official debian package once its available, if I really want to know...
