This is not an error but an informational message.

The PDB files are providing the debug information (symbol names) when stepping through code inside the corresponding module. Because you will probably want to debug your code and not third party modules, you can ignore the message.

@Jochen, you are right! i can ignore message from third party module. When i am debugging my code throw a exception from heap manager. For that reason i need to understand each module debugging process. Here is my VC++ call stack track report;
Exception throw at Line 70;

ntdll.dll!_RtlpBreakPointHeap@4() Unknown
ntdll.dll!_RtlpCheckBusyBlockTail@8() Unknown
ntdll.dll!_RtlpValidateHeapEntry@12() Unknown

If you have any idea please do replay.

Don't bother with binary code from other modules. Try to identify the error in your program.

The above call stacks show that there may be a heap curruption when freeing the pBlock memory. A common reason is that you write to another allocated buffer out of bounds (e.g. the one in memory before pBlock when using an index at or a little bit above it's size).

Overall you should try to locate the error yourself because finding it requires inspecting all involved source code lines which is rather impractical for an online forum like CodeProject.
