The problem is that there are two TRANSLATION_UNIT_DECLs.  One appears to come from the PCH file, 
and is incomplete.  I am not sure where the other one comes from; possibly it is created after the PCH 
file is loaded.  There should, of course, be only one TRANSLATION_UNIT_DECL, since there is only one 
translation unit.  So, I suspect a problem with the timing of PCH saving and/or restoring.

I've confirmed that this crash does not happen immedately before Zack's 2004-03-23 patch, and does 
happen immediately after it was applied.  I find it particularly suspicious that this patch introduced a 
number of constructs of the form "if (pch_file) return;"; such constructs were not necessary before, and 
it is likely that these are bandaids for deeper problems.
