为什么 WinDBG 会lmv
显示两个版本信息字段(当我知道没有其他工具可以做到这一点时)以及在哪些情况下这些字段会有所不同?
背景:我有一个我们的应用程序的实时转储(来自死锁)。符号已正确加载,我能够将死锁追溯到微软的pdm.dll
(用于我们的 vbscript 引擎的“进程调试管理器”)。
然后,我想检查在生产站点的会话中加载了该 DLL 的哪个版本:
0:000> lmv m pdm
start end module name
51860000 518b8000 pdm # (pdb symbols) d:\symcache\pdm.pdb\7BE601EDE9234816B72B49DA4A25DF042\pdm.pdb

如您所见,文件和产品版本显示了两次,但它们在转储中不匹配!
当我在我的机器上交叉检查(显然,查看时间戳和校验和!)运行 iexplore 进程的相同文件时:
0:043> lmv m pdm
start end module name
3efa0000 3eff8000 pdm (pdb symbols) c:\windows\symbols\martin-cache\pdm.pdb\415D0A165EB24613BC01CE516512062C2\pdm.pdb

版本信息匹配。
