windgb调试dmp ，提示堆栈溢出。怎么查看是哪个地方出错？

iis程序池挂掉了，用windgb调试w3wp.exe.dmp获取到信息：

This dump file has an exception of interest stored in it.

The stored exception information can be accessed via .ecxr.

(18dc.215c): Stack overflow - code c00000fd (first/second chance not available)

000007fe94042e8e 48896500 mov qword ptr [rbp],rsp ss:0000000007d75f80=0000000000000000

第一次使用windgb，也不太会汇编，请问怎么找到程序出错的地方？
