You're right, I just disabled it again. Sorry for the fuss.

I just wanted to be sure. I didn't mean enabling the DHT was a mistake.
However, I would have suggested to disable the DHT as a quick fix
if you just wanted to get rid of the crashes. Your bug report is
certainly welcome.

What irritated me is that your backtrace shows ATOM_STRING instead of
ATOM_GUID but I think that can be ignored.

The source of the crash is atom_guid_free() in rpc_cb_free(). I've
added some consistency checks in current SVN to catch incorrect
handling sooner. I strongly suspect rpc_cb_free() is called more
than once for the same item.

I haven't experienced any crash like that myself. It could help
if you tried gtk-gnutella from current SVN. Also compiling with
maximum gdb debug information and disabled optimization like this

./build --cflags='-g3 -O0'

might yield an even more informative backtrace.

Just upgraded to Ubuntu Jaunty (9.04), and when recompiling GtkG (svn 16499), I am seeing tons of the warning message "ISO C forbids braced-groups within expressions".  Here's a sampling:

In file included from parq.h:43,
                 from uploads.c:59:

It seems that every assert throughout GtkG is triggering this warning (and there are a LOT of them :)).

I suspect this is a result of picking up a new gcc version with the upgrade.  Here's the version I'm using:

lloyd@dell:/usr/local/src/gtk-gnutella$ gcc -v
Using built-in specs.
Target: i486-linux-gnu
Configured with: ../src/configure -v --with-pkgversion='Ubuntu 4.3.3-5ubuntu4' --with-bugurl=file:///usr/share/doc/gcc-4.3/README.Bugs --enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr --enable-shared --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-nls --with-gxx-include-dir=/usr/include/c++/4.3 --program-suffix=-4.3 --enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc --enable-mpfr --enable-targets=all --with-tune=generic --enable-checking=release --build=i486-linux-gnu --host=i486-linux-gnu --target=i486-linux-gnu
Thread model: posix
gcc version 4.3.3 (Ubuntu 4.3.3-5ubuntu4)

Any clues?

Do you compile with GLib 1.2?

No, it's caused by -pedantic in the C compiler flags.
 
> Any clues?

GCC is right. This particular warning is quite useless here and GLib 2.x manages
to avoid or at least suppress it. Unfortunately, there doesn't seem to be a
compiler switch to supress it. It doesn't even seem to be possible to override
-pedantic unlike other switches. At least, I have no glue.

Overall though, use of -pedantic makes it easier to keep the code portable and
ISO-compliant, as far as reasonable and possible.
