To interpret this, you need to look up the definition of the TEB data structure. For maximum versatility, assume you have no symbols and use the dd (Display Memory) command to display the raw values at that location: 0:002> dd 7ffdc000 L4Д§ffdc000 009fdef0 00a00000 009fc000 00000000 However, this requires you to have the proper symbols. The easiest way to list it is using !teb. The stack information is contained in the TEB (Thread Environment Block) at 0x7FFDC000. The period at the left of this line indicates that this is the current thread.

The process has multiple threads, but the important one is the one that caused the overflow, so identify this thread first using the ~ (Thread Status) command: 0:002> ~*kД id: 570.574 Suspend: 1 Teb 7ffde000 UnfrozenДЎ id: 570.590 Suspend: 1 Teb 7ffdd000 Unfrozen Now you should investigate the stack usage of the target process. The target thread has broken into COMCTе…ѓ2!_chkstk, which indicates a stack problem. 0:002> !error 0xC00000FDД®rror code: (NTSTATUS) 0xc00000fd (3221225725) - A new guard page for the stack cannot be created.

You can also use the !error command to look up errors in the Windows Debugger. All of the status codes are listed in 2.3.1 NTSTATUS Values.

You can look up exception code 0xC00000FD in ntstatus.h, This exception code is STATUS_STACK_OVERFLOW, which indicates A new guard page for the stack cannot be created. Last event: Exception C00000FD, second chance

The first step is see what event caused the debugger to break in: 0:002>. See Controlling the User-Mode Debugger from the Kernel Debugger for details. In this example, NTSD is running on the same computer as the target application and is redirecting its output to KD on the host computer.

Here is an example of how to debug a stack overflow. Debugging a stack overflow without symbols For additional information on these base concepts, refer to Microsoft Windows Internals by Mark Russinovich and David Solomon. This topic assumes general knowledge of concepts, such as threads, thread blocks, stack and heap. For example, by the /F (Set Stack Size) - C++ Compiler Option. The amount of optimization is influenced by compiler settings applied at build time. The compiler might also be able to eliminate some local variables entirely by optimizing calculations.

For example, if two variables are in different scopes, the compiler can use the same stack memory for both of those variables. However, the compiler usually performs optimizations that reduce the stack space required by a function. The amount of stack space required by the function could be as large as the sum of the sizes of all the local variables. When a function running on a thread allocates local variables, the variables are put on the thread's call stack. This is often caused by infinite recursion.ДЄ thread cannot extend the stack because the page file is maxed out, and therefore no additional pages can be committed to extend the stack.ДЄ thread cannot extend the stack because the system is within the brief period used to extend the page file. There are three possible causes for this error:ДЄ thread uses the entire stack reserved for it. A stack overflow is an error that user-mode threads can encounter.
