I can assume that 10M stack is reasonable for C code, where it's usual to allocate temporary buffers on stack (in C++ it's easier to use heap, e.g. using std::vector).<br><br>Bad thing is - impact of this flag is detected only at run time. If with /Zm your code just won't compile, with /STACK everything compiles and links perfectly, works fine in simple cases, but you'll receive OOM under load (in C, when stack will be over).<br>
That's why I didn't insist on changing behavior when found this bug 3 years ago.<br><br><div class="gmail_quote">On Tue, Jan 31, 2012 at 8:02 PM, Glenn Coombs <span dir="ltr"><<a href="mailto:glenn.coombs@gmail.com">glenn.coombs@gmail.com</a>></span> wrote:<br>

</div><br>can you check if ITK and VTK build fine without the large stack size argument (/STACK:10000000) as well ?<span class="HOEnZb"><font color="#888888"><br>

ITK and VTK both build fine if I remove the /Zm1000 flag.<br>
