By the way, I seriously doubt /GS is the cause of your errors. It *might* be the case
that /GS is *detecting* errors that previously existed, in which case the solution is
obvious: fix the bugs!

I've not had a problem using this switch in 2005. My guess: some memory got
rearranged somewhere revealing a problem that was already in the code.

Joe,

I've seen stranger messages. :o)

So have I, including a MessageBox that contained ONLY the error icon (no text, no
caption). But I suspect that this is NOT what actually happened in this case.

Hi @all,

of caouse you want to see some more information an I think I have some now.

First of all, I'm quite confident that there might be some buffer overruns
and some
resource leaks, but we're on that problem. Nevertheless the software should
not
crash that way. The same binaries run without any crashes on Windows XP SP2.
So that lead me to a Vista related issue. Another issue is, that we are
talking about
a non deterministic error which not reliable reproducable.

Here is the problem signature, we're dealing with an access violation...
