Albert Strasheim updated AMQCPP-58:
-----------------------------------
Attachment: socketleak1.diff
Patch for leak that happens when createConnection fails due to broker being
down.
This patch includes a type of fix for an issue that might also exist elsewhere
in the code: BufferedSocket wasn't properly initializing its pointer fields to
zero (and its other fields to useful default values), causing its destructor to
crash when deleting it (after connect had failed).
The program I attached previously still seems to leak when reestablishing
connections to the broker after it has been up and gone down. I just can't
figure out how this leaks yet.

> There seems to be a memory leak when running the example program from
