    2525Symbol search paths are used to inform the debugger where it might be able to find the symbol files related to the modules loaded in memory.  Entries prefixed with 'srv*' are used to denote a web based symbol store. DbgHelp will use them if symsrv can be loaded at the time of the crash.
    … …  
    4545If the correct symbol file can be found, it'll display what symbol file type is in use.  The three most common symbol types in modern software are 'PDB', 'exports', and  '-no symbols-'. Symbol files are pretty large and so most projects do not like to include  them as part of the APP VERSION package. Luckily Microsoft has created a technology called Symbol Stores which enable an application to be able to grab its symbol file from a web server at the time of a crash in a compressed format. We will describe setting up a symbol store later in this document.

    47 PDB files are generated at compilation time and usually have to be turned on for release builds. This file will contain all the needed information to generate a pretty good  callstack which you can use to diagnose problems.

    4949Export symbols usually only appear on DLLs since DLLs can export function pointers via the export table. When you see this in the module list you'll only see functions which  are listed in the export table in the callstack.

    106 This section if included in the thread describes what event ocurred that caused the runtime debugger to engage. Structured Exceptions in Windows are not the same thing as C++ exceptions. Unless you are using a compiler that knows about both types it is unlikely that a C++ catch is going to actually catch this type of exception.

    112112The example above shows that  EXCEPTION_BREAKPOINT(PlatformSDK\Include\winbase.h) was raised at 0x7C822583. EXCEPTION_BREAKPOINT is defined as STATUS_BREAKPOINT(PlatformSDK\Include\ntstatus.h) which is defined as ((NTSTATUS)0x80000003L).

    207 You'll need to explictly name both your EXE and PDB before compilation since the debugger bases the name of the PDB file off of information that is stored in the executable header.
