Debian Bug#502320: libopenusb0: race condition
Thu, 16 Oct 2008 01:19:27 +0200
it appears to me that there is some sort of a race condition there. I
haven't investigated yet, though, but wanted to run it by you.
----- Forwarded message -----
There appears to be a race condition inside the Linux plugin for libopenusb.
The last reference on a connection was dropped without closing the
connection. This is a bug in an application. See dbus_connection_unref()
documentation for details.
Most likely, the application was supposed to call dbus_connection_close(),
since this is a private connection.
is output on amd64 a varying number of times, occasionally followed by a
segmentation fault. On powerpc, it appears to work fine, but the race can
be triggered by attaching a debugger to the "main" thread.
