Client closes connexion immediately after long CreateSessionResponse

Description

In the client, the logs show some messages about invalid secure channel Id:

Toolkit (Error) ChunksMgr: invalid secure channel Id=1426261536 expected Id=7 (epCfgIdx=0, scCfgIdx=2)

However, the Wireshark traces show that the scId is correctly sent by the server.

Analysis

The problem is encountered with large responses. Further analysis with a fake_server replaying a buggy trace shows that the bug only appears when the response is received through multiple SOCKET_RCV_BYTES events.

The debugger trace shows that the latter bytes are always written at the 8th position of the chunk buffer.
