The second check is where the trap occurred:

if (!pciParent
!*pciParent->pszFileName !hwndCnr) flesh.c ~279

there are some clues. It almost seems like pciParent was not yet fully initialized when the trap occurred. By our rules, under normal conditions, pszFileName is never NULL.

EDX points to pciParent, so we can look at its contents. At the time the ..trp file was written [edx+0x20] contains a valid pointer. You may have an SMP timing race.

I have a full trap dump pdump.292

Since I have now seen several traps due to pci->pszFileName being NullStr. I will add this check which should eliminate this trap. CS[1832]
