3036	Segmentation fault at boost::asio	elod.biro@…	chris_kohlhoff	"We use the boost 1.33.1 version and we are upgrading the boost to 1.39.0.

We use the boost to handle the network connection in our software.
Sometimes the program crashes, but we dont know exactly in what cases these are. When the program crashes, the result of the core analyses always the same:

Program terminated with signal 11, Segmentation fault.

We dont know if we use the boost badly or it is a boost bug.
We use the 1.33.1 version and we are upgrading the boost to 1.39.0.
This problem is urgent for us and at least it would be good if we knew if the problem is in boost or in our program.
Thank you for any information!
