winDbg causing problems

I have a strange problem, my driver runs without a crash normally,
however when windbg is connected this is what i see

Breakpoint 0’s offset expression evaluation failed.
Check for invalid symbols or bad syntax.
WaitForEvent failed
nt+0x59082:
80537082 8945fc mov [ebp-0x4],eax
kd> bl
0 du 0001 (0001) (dummmy!DriverEntry)

I have the correct symbols, and path set in the debugger, and this
break point is disabled, then why does the kernel panic?

Let me guess … you were unlucky enough to install 6.4 or 6.5? This is the
same behavior I have seen with versions 6.4 and 6.5. It seems that these
versions of WinDbg are easily confused about where and how to use symbols,
even going so far as to have an unrecognizable breakpoint that you cannot
get around until you provide the proper symbology. Which sometimes you can’t
because the symbol file you are trying to replace is held by WinDbg causing
your build to bomb when it creates the PDB file. Doing a “!reload -u” has to
large a chance on 6.4 and 6.5 of not working so your only alternative is to
kill WinDbg, build the symbols, and the restart… Even booting the target
and doing the host build right after the target resets, will not allow the
PDB file to be built. I have so spent much time trying to get symbols
usable, that I finally said screw it and fell back to 6.3. I would rather
debug my code than debug a debugger.

To the WinDbg developers:

I am more than willing to tell you what my target environment is to permit
you to stage a system that evidences the same problem. I’ll even provide
dumps and other information I can acquire, within reason, tat may help you
resolve issues. However, an honest evaluation of what I have seen so far
with 6.4 and 6.5 is that there was insufficient testing before the release.
I will provide what info I can, but frankly, debugging the debugger has cost
me time over the past two weeks that I can ill afford, and unfortunately
schedules don’t have places in them for faulty WinDbgs. (Sometimes my boss
thinks I am a wind bag.)

but this thread best belongs in the WinDbg forum.

I setup my development builds and my debugger so that the target
directory is NOT where I point windbg at to find the symbols for test
drivers/exes. That way the worst case is that windbg is looking at the
wrong symbols and not that I can’t build because the pdb file is locked.
I just have to remember to refresh the test directory as well as the
target system. That is error prone of course, but I’ve taken care of
that for all but boot drivers by using a map file.

Until 6.4/6.5 it really wasn’t a problem. In 6.3 I find that “!reload -u
” is quite effective in releasing the PDB file. In 6.4/6.5 that
simply does not work reliably. The only reliable did I did find was to close
WinDbg, build and then restart it.6.4/6.5 are simply not worth the time or
effort to try to use them.
