You also need to know which module the offset belongs to, if you get 0xC0000008 ( STATUS_INVALID_HANDLE ), then the exception will most likely be thrown from the ntdll.dll file, which will not help you debug your program, because what you need is deeper on the stack.
What you need to do is provide LocalDumps to the client, and then send you a minidump file that you can debug.
Example registry settings:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps] "DumpFolder"="d:\\miniDumps" "DumpType"=dword:00000002 "CustomDumpFlags"=dword:00001124
