x64 Platform Bug? Call Stack doesn't show. by minoos

We have identified and fixed the problem in our stack unwinding engine. The fix will definitely be included in our next major release. Meanwhile we are considering whether to include this fix in our upcoming VS 2012 VSUpdate.

Thank you very much for taking the time to report this problem to us.

Simplest sample code is here,

//////

#include "stdafx.h"

int _tmain(int argc, _TCHAR* argv[])
{
    char s[800000];

    s[0] = 0;
}

///////////

and, just click F11 ( Step Into )... call stack contents is empty. ( 64bit debug )

in disaseembly window,

void func()
{
000000013F903040 push        rdi
000000013F903042 mov         eax,0C3550h
000000013F903047 call        __chkstk (13F901260h)
000000013F90304C sub         rsp,rax <-- after step here, call stack is clear.
000000013F90304F mov         rdi,rsp
000000013F903052 mov         ecx,30D54h
000000013F903057 mov         eax,0CCCCCCCCh
000000013F90305C rep stos    dword ptr [rdi]
000000013F90305E mov         rax,qword ptr [__security_cookie (13F909028h)]
000000013F903065 xor         rax,rsp
000000013F903068 mov         qword ptr [rsp+0C3540h],rax

Hi minoos, thanks for submitting feedback on Visual Studio and .Net Framework. Do you mean you can't open the Call Stack window?
>> No, Call Stack Window is Opened. But, Window Content is empty. Like as call stack is broken.

at 32bit debug, call stack is >

    TestHeap3.exe!wmain(int argc, wchar_t * * argv) line 17    C++
    TestHeap3.exe!__tmainCRTStartup() line 552 + 0x19 bytes    C
    TestHeap3.exe!wmainCRTStartup() line 371    C
    kernel32.dll!765533aa()     

but at 64bit debug, call stack is empty.
and main window represent "No symbols are loaded for any call stack frame. The source code cannot be displayed."
