<h3>disable_stackalloc</h3>
<p> Controls the compiler method used to grow the size of the stack.</p>
<h5>Syntax</h5>
<p class="code">#pragma disable_stackalloc on | off | reset</p>
<h5>Targets</h5>
Intel x86<br />
<h5>Remarks</h5>
<p>The compiler controls how stack space is grown as follows:</p>
<ul>
<li>off – for each object on the stack larger than 4096 bytes, the compiler calls a runtime routine to touch each new page on the stack to tell the OS to allocate more stack space.</li>
<li>on – the compiler only touches the last (topmost) page of the stack after allocating local space.</li>
</ul>
<p class="note"><strong class="note">NOTE</strong> Use of this pragma is required for Win32 code.</p>
<p>This pragma does not correspond to any panel setting. To check this setting, use the <span class="code">__option (disable_stackalloc)</span>. The default setting for Win32 targets is off.<br />
