Windbag not showing all the locals?

I’m having a bit of a tear the hair out problem with windbg 6.1.0017.0
here. To be specific its not showing me all of the local variables (makes
the debugging a bit tricky). To be specific I am looking at a full crash
dump on W2K SP3 after PAGE_FAULT_IN_NON… and what I can see is
consistent with a garbage pointer dereference. Is there some limitation is
windbg here?

If this is optimized code then some local variables may have been
optimized away…

I’ve seen the same problem in unoptimized code w/ this build of the debugger.

Seems to happen more with variables that are assigned in the same line that they’re declared (e.g. “char *ptr = NULL” kind of things tend to now show in the Locals window).

lclarke: What does !lmi show for the module you are trying to
debug / look at locals?

SMcDowell: Do you have a code snippet from a real piece of code that
demonstrates the issue? This doesn’t sound like anything we have seen.
Also a !lmi and/or a minidump of your process with matching
PDB/EXE + full source file (for line number matching) would be useful.

If you have problems with the Windows debuggers I recommend you post the
issues to the microsoft.public.windbg newsgroup.

Somewhat embarassed. Its free build, so, yes, optimised.

Sometimes a .reload will clear it up also…
