Windbg still not releasing handle to .pdb

So I am still seeing this upon occasion. I have no watch expressions, no breakpoints; I do an unload of a specific DLL and WinDbg keeps a handle open to the .PDB still.

-Jeff

Pretty much; I know of at least one other person whom I trust that has seen this as well.

I haven’t seen it a whole lot, but it has been uncommon either. I haven’t bothered to try to
reproduce it, nor have any intention of doing so, as it seems like a forgone conclusion to me at
this point that what I will get back from msft if work this up is at best an e-mail saying they
couldn’t reproduce it.

Please try the latest debugger. We found out and fixed a possible problem there. If you continue hit the PDB handle issue from the latest release, please let us know and we will try repro the fix them.

Thanks,

I reported it last month, but I’m still hitting it frequently with the
latest available release…

For me, it seems to be most evident when debugging applications launched by
WinDBG (Ctrl+E). Over the last couple of days I resorted to having
ProcessExplorer’s “search handle” dialog up so I can close the 1-4
outstanding handles without having to quit WinDBG between builds.

+1 as far as having seen with 6.11.1.402, and also as far as reporting it, though to be fair, I
didn’t report it via the windbg alias, but I was told that the windbg folks already knew about it.
I don’t really know what happened, but I guess that it doesn’t really matter either, as at least the
ever dependable Snoone reported it.

As far as the conditions involved, I have no idea, other than to say that mine had to be different,
as Ctrl+E was totally unknown to me until just now.

Please verify your debugger version. Is it 6.11.1.402 or 6.11.1.404? There should be another debugger update (6.11.1.404) in early March that fixes one PDB handle issue we finally found out. The site http://www.microsoft.com/whdc/devtools/debugging/default.mspx does not update the version, but if you click the link and upgrade, it should be build 404.

If you still repro the problem from 6.11.1.404, please let us know and we will look into this.

Thanks,

Spooky! OK, just downloaded dbg_x86_6.11.1.402.msi, which installed version
6.11.1.404.

Anything else different in this release or just the PDB fix?

Just thought I’d mention that after almost two weeks of beating on it, I
haven’t seen the PDB lock problem again. Looks like the demon has been
expelled!
