Windbg - !clrstack

问题:

I'm attempting to debug a manual dump file of a 64bit w3wp process with 64bit Windbg (Version 6.10). The dump was taken with taskmgr. I can't get anything from the !clrstack command. Here is what I'm getting:

!loadby sos clr

!runaway

!clrstack

GetFrameContext failed: 1

What is GetFrameContext failed: 1?

回答1:

Use !dumpstack command instead of !clrstack. It usually works.

回答2:

Try getting the "native" call stack by doing "k" and see what that gets you. Sometimes, the stack isn't quite right and the !ClrStack extension is pretty sensitive.
