[dbus-cplusplus-devel] Ref counter system not thread safe?

[Nicolas P. <npa...@wy...>]

I everybody. I m occasionnaly working with DBus C++ and pushing it to its 
highest limits.

The following traces show a failure condition that happens sometime when I ran 
a very long test making heavy use of DBus C++. The program contains one 
adaptor and several proxies. It is a threaded environment.

Program received signal SIGBUS, Bus error.
[Switching to thread 1546]
0x004178c8 in DBus::RefCnt::noref (this=0x45c4a8) 
at /usr/targets/081119-1.1.13-debug/root/usr/include/dbus-c++-1/dbus-c++/util.h:72
72                      return (*__ref) == 0;
(gdb)
Continuing.
Program terminated with signal SIGBUS, Bus error.
The program no longer exists.
(gdb)

It seems the the ref counter is broken. This is probably due to a race 
condition between unref/noref but it is still quite blur for me. From what i 
saw the ref counting sytem is not thread safe. Any idea how this could be 
solved?

I am working with version 0.5 (AC_INIT([libdbus-c++], 0.5.0, 
[sh...@gm...])). Since the ChangeLog is not up to date i can't figure 
out if something like that was fixed or not, so I need your help.

Thanks a lot.
