I found the offending file and repaired it. I opened it in LDT 2004 and
Audit runs clean. I then starting stepping through the layout tabs and after
about 4 tabs ACAD crashes with a runtime error and then leaves the message
shown in the attached screen cap. I am suspecting the problem is a memory
issue as it seems the viewport cache is over loading and crashing ACAD.
There is no one layout tab that crashes it. I can pick them in any order and
they load fine until about the 4th tab where it crashes. Civil 3D takes much
longer to load the layouts and it crashes on the 1st or 2nd tab that I pick.
I think it is using more memory which is causing it to crash sooner.
I'm running a new Dell Precision 490 Workstation with Dual Xeon 5110's, 3GB
Ram, Nvidia Quadro FX 3400 video with 256 MB, Win XP Pro SP2.

More to the story. Audit in C3D 2009 does not find any errors even after
several runs. Audit in LDT 2004 finds 8 errors, then 24 errors on the second
pass and cannot repair it so there is a problem in one of the XREF's. This
may account for the crashing in the other drawings as well. What is
troubling is C3D is not detecting the errors at all. Is there a difference
in how C3D handles XREF's that may be the reason?

I have been trying to open some legacy Land Desktop 2004 drawings in C3D
2009. When I try to view layout tabs, Civil3D closes without warning. I have
tried Recover and Audit with no errors and the same results. The drawings
open fine in Land Desktop 2004. This has happened on a couple of drawing
files so far.
