[krbdev.mit.edu #7353] assertion failure (possible memory corruption) when restarting putty session

[Benjamin Kaduk via RT]

asedeno reports:
Start a (GSSAPI-authed) connection in PuTTY, pull the network connection so the putty 
session drops, reenable network, and right-click the title bar to restart the connection.
Then, observe the "Assertion failed!" dialog box:

Program: C:\Users\zonetest\desktop\putty.exe
File: .\threads.c
Line: 337

Expression: destructors_set[keynum]==0

For more information on how your program can cause an assertion failure, see the Visual 
C++ documentation on asserts.

When using the signed beta9 KfW, attaching visual studio and looking at the stack trace 
seemed to implicate the gssapi32 library; however, doing a rebuild with debugging symbols 
changes the stack trace so that our library is no longer included...
