Hi all,

Recently we have been seeing a lot of vnc E4.6.0 crashes on our system and on debug we see that all the vnc sessions crash with segfault at same rip.

kernel: Xvnc-core[10007]: segfault at 0000000000000000 rip 0000000000550279 rsp 00007fffffffd110 error 4

And upon debugging about the RIP, we found this instruction at which vnc is crashing
0x0000000000550279
    <_ZN3vnc11SSecurityS333readSessionIdChallengeAndResponseEv+15049>:   mov
    (%rax),%rsi

Any comments/thoughts on what this function might be doing, and the specific point of crash. This crash is happening every time at the same place.

Thanks
Rajeev
