Why isn't SymGetSymFromAddr64 working? It returns error code 126

Question

I am trying to capture a stack trace on exceptions using the following code:

#include \"stdafx.h\"
#include 
#include 
#incl

Had the same problem with your code.

Fixed it with:

HANDLE process = GetCurrentProcess();
SymInitialize( process,NULL,TRUE );

Note: now, the SymGetLineFromAddr64 fails for some big address, with error 487 (ERROR_INVALID_ADDRESS)

Use the following for tracing:

printf("Error from SymGetLineFromAddr64: %lu for address 0x%I64x.\n",
       GetLastError(),
       frame.AddrPC.Offset);

EDIT: when I use the Go to Disassembly in my Visual Studio and enter the fist address which make SymGetLineFromAddr64 fail (here, it's 0x000000005a03da08), it shows the source code for:

f:\dd\vctools\crt_bld\self_x86\crt\prebuild\eh\throw.cpp
