I ran kd by mistake and got some output that inteerested me, a reference to a line of code in my module that I can't see on the call stack of any thread. The lines weren't the beginnning of the method so I don't think the reference is to a function pointer, but possibly the result of an exception being stored in memory??? Of course, that...
Short Version I want an ADPlus script that will do a full memory dump on the first-chance StackOverflowException, before anything is cleaned up, and ignore all other exception types.

VS2005 C# Compiler crashes during our team's nightly build process. I attach to it with WinDBG, load SOS extensions, print the callstack, but cannot see exception info.

Many Windows system files are available from Microsoft through a download page or http path. My WinDbg can't find the symbol files for VBScript.dll and ASP.dll and I can't seem to find them on the Internet. The VBScript.dll on the server is 5.6.0.8835 and the ASP.dll is 6.0.3790.4195. Both have younger file dates than their symbol fil...
A customer is attempting to capture a minidump of a hang. He fires up WindDbg and successfully attaches to the process.

I have a native release dll that is built with symbols. There is a post build step that modifies the dll. The post build step does some compression and probably appends some data. The pdb file is still valid however neither WinDbg nor Visual Studio 2008 will load the symbols for the dll after the post build step. What bits in either ...
I think I'm missing some fundamentals here so hopefully this post can clarify this. I've taken a dump and am looking at the managed heap and am interested in looking specifically at what objects are within each heap. Here is the output from the debugger: 0:000> !eeheap -gc Number of GC Heaps: 1 generation 0 starts at 0x3cca447c generat...
Generated a debug diagnostic dump file for a COM+ application. Upon analysis look like threads deadlocks at line OLE32!SwitchSTA. My symbol path is pointing to msdl.microsoft.com/download/symbols.

I'm trying to learn about reverse engineering, using Minesweeper as a sample application. I've found this MSDN article on a simple WinDbg command that reveals all the mines but it is old, is not explained in any detail and really isn't what I'm looking for. I have IDA Pro disassembler and the WinDbg debugger and I've loaded winmine.exe...

Occasionally when you exit, the app appears to go away but task manager sho...
