Error diagnosis

[SteveB]

Hello All

We have an app that was written a few years ago in which the developers

wrote an entire exception handling system.
I have a problem with the following line if code:
OutStream << L" (+ " << std::dec <<
static_cast<DWORD>(Disp64) << L" bytes), ";
This is throwing the following exception:
Run-Time Check Failure #2 - Stack around the variable 'stIHM' was
corrupted.
I was wondering if anyone could interpret what the line of code is
actually doing and what the error means - a Google search has proved
fruitless
Thanks
Steve

What the line of code is actually doing depends on what type OutStream
is and how the op<<'s have been defined.

Based on the wording, I assume the error means that some piece of code
is clobbering your stack (i.e., writing to memory it doesn't have rights
to.) To find the real meaning, you will have to investigate your code
and or ask in a newsgroup that discusses your runtime system.

My bet is that you overwrite memory somewhere else and here
only the error is discovered.

<OT>You might want to use a tool such as electricfence or valgrind
to find the exact spot.

I'll look into these apps, thanks
