I am using Stackdumps with Win32, to write all return adresses into my logfile. I match these with a mapfile later on (see my article [Post Mortem Debugging][1]).
EDIT:: Problem solved - see my own answer below.
With Windows x64 i do not find a reliable way to write only the return adresses into the logfile. I tried several ways:
Trial 1: Pointer Arithmetic:
CONTEXT Context;
RtlCaptureContext(&Context);
char *eNextBP = (char *)Context.Rdi;
for(ULONG Frame = 0; eNextBP ; Frame++)
{
char *pBP = eNextBP;
eNextBP = *(char **)pBP; // Next BP in Stack
fprintf(LogFile, "*** %2d called from %016LX (pBP at %016LX)\n", Frame,
(ULONG64)*(char **)(pBP + 8), (ULONG64)pBP);
}
This works fine in the debug version - but it crashes in the release version. The value of Context.Rdi has no usable value there. I did check for differences in the compiler settings (visual Studio 2005). I have not found anything suspicious.
Trial 2: Using StackWalk64
RtlCaptureContext(&Context);
STACKFRAME64 stk;
memset(&stk, 0, sizeof(stk));
stk.AddrPC.Offset = Context.Rip;
stk.AddrPC.Mode = AddrModeFlat;
stk.AddrStack.Offset = Context.Rsp;
stk.AddrStack.Mode = AddrModeFlat;
stk.AddrFrame.Offset = Context.Rbp;
stk.AddrFrame.Mode = AddrModeFlat;
for(ULONG Frame = 0; ; Frame++)
{
BOOL result = StackWalk64(
IMAGE_FILE_MACHINE_AMD64, // __in DWORD MachineType,
GetCurrentProcess(), // __in HANDLE hProcess,
GetCurrentThread(), // __in HANDLE hThread,
&stk, // __inout LP STACKFRAME64 StackFrame,
&Context, // __inout PVOID ContextRecord,
NULL, // __in_opt PREAD_PROCESS_MEMORY_ROUTINE64 ReadMemoryRoutine,
SymFunctionTableAccess64, // __in_opt PFUNCTION_TABLE_ACCESS_ROUTINE64 FunctionTableAccessRoutine,
SymGetModuleBase64, // __in_opt PGET_MODULE_BASE_ROUTINE64 GetModuleBaseRoutine,
NULL // __in_opt PTRANSLATE_ADDRESS_ROUTINE64 TranslateAddress
);
fprintf(gApplSetup.TraceFile, "*** %2d called from %016LX STACK %016LX FRAME %016LX\n", Frame, (ULONG64)stk.AddrPC.Offset, (ULONG64)stk.AddrStack.Offset, (ULONG64)stk.AddrFrame.Offset);
if(! result)
break;
}
This does not only dump the return addresses, but the WHOLE STACK. I receive about 1000 lines in my log file using this approach. I can use this, but i have to search trough the lines and some data of the stacks happens to be a valid code address.
Trial 3: Using Backtrace
static USHORT (WINAPI
*s_pfnCaptureStackBackTrace)(ULONG, ULONG, PVOID*, PULONG) = 0;
if (s_pfnCaptureStackBackTrace == 0)
{
const HMODULE hNtDll = ::GetModuleHandle("ntdll.dll");
reinterpret_cast<void*&>(s_pfnCaptureStackBackTrace)
= ::GetProcAddress(hNtDll, "RtlCaptureStackBackTrace");
}
PVOID myFrames[128];
s_pfnCaptureStackBackTrace(0, 128, myFrames, NULL);
for(int ndx = 0; ndx < 128; ndx++)
fprintf(gApplSetup.TraceFile, "*** BackTrace %3d %016LX\n", ndx, (ULONG64)myFrames[ndx]);
Results in no usable information.
Has anyone implemented such a stack walk in x64 that does only write out the return adresses in the stack? Ive seen the approaches [StackTrace64][2], [StackWalker][3] and other ones. They either do not compile or they are much too much comlicated. It basically is a simple task!
Sample StackDump64.cpp
#include <Windows.h>
#include <DbgHelp.h>
#include <Winbase.h>
#include <stdio.h>
void WriteStackDump()
{
FILE *myFile = fopen("StackDump64.log", "w+t");
CONTEXT Context;
memset(&Context, 0, sizeof(Context));
RtlCaptureContext(&Context);
RtlCaptureContext(&Context);
STACKFRAME64 stk;
memset(&stk, 0, sizeof(stk));
stk.AddrPC.Offset = Context.Rip;
stk.AddrPC.Mode = AddrModeFlat;
stk.AddrStack.Offset = Context.Rsp;
stk.AddrStack.Mode = AddrModeFlat;
stk.AddrFrame.Offset = Context.Rbp;
stk.AddrFrame.Mode = AddrModeFlat;
for(ULONG Frame = 0; ; Frame++)
{
BOOL result = StackWalk64(
IMAGE_FILE_MACHINE_AMD64, // __in DWORD MachineType,
GetCurrentProcess(), // __in HANDLE hProcess,
GetCurrentThread(), // __in HANDLE hThread,
&stk, // __inout LP STACKFRAME64 StackFrame,
&Context, // __inout PVOID ContextRecord,
NULL, // __in_opt PREAD_PROCESS_MEMORY_ROUTINE64 ReadMemoryRoutine,
SymFunctionTableAccess64, // __in_opt PFUNCTION_TABLE_ACCESS_ROUTINE64 FunctionTableAccessRoutine,
SymGetModuleBase64, // __in_opt PGET_MODULE_BASE_ROUTINE64 GetModuleBaseRoutine,
NULL // __in_opt PTRANSLATE_ADDRESS_ROUTINE64 TranslateAddress
);
fprintf(myFile, "*** %2d called from %016I64LX STACK %016I64LX AddrReturn %016I64LX\n", Frame, stk.AddrPC.Offset, stk.AddrStack.Offset, stk.AddrReturn.Offset);
if(! result)
break;
}
fclose(myFile);
}
void funcC()
{
WriteStackDump();
}
void funcB()
{
funcC();
}
void funcA()
{
funcB();
}
int main(int argc, char *argv[])
{
funcA();
}
Running this sample results in the follwing log file content:

I finally found a reliable way to log the stack frames in x64, using the Windows function CaptureStackBackTrace(). As I did not want to update my SDK, I call it via GetProcAddress(LoadLibrary());
typedef USHORT (WINAPI *CaptureStackBackTraceType)(__in ULONG, __in ULONG, __out PVOID*, __out_opt PULONG);
CaptureStackBackTraceType func = (CaptureStackBackTraceType)(GetProcAddress(LoadLibrary("kernel32.dll"), "RtlCaptureStackBackTrace"));
if(func == NULL)
return; // WOE 29.SEP.2010
// Quote from Microsoft Documentation:
// ## Windows Server 2003 and Windows XP:
// ## The sum of the FramesToSkip and FramesToCapture parameters must be less than 63.
const int kMaxCallers = 62;
void* callers[kMaxCallers];
int count = (func)(0, kMaxCallers, callers, NULL);
for(i = 0; i < count; i++)
printf(TraceFile, "*** %d called from %016I64LX\n", i, callers[i]);
For vs2008 x64: Based on https://msdn.microsoft.com/en-us/library/windows/desktop/bb204633%28v=vs.85%29.aspx and RED SOFT ADAIR:

We use minidumps exclusively here. You can generate a stripped down one that just includes stack information and dump out a stack trace from a decent debugger later.
It doesn't solve your problem directly, but I think it will provide you a much better postmortem reporting mechanism.
