>Do we have a list of known causes for C5 in VFP7?


Sadly, no.
Some even thought, likely because the (alleged) error list that exists showed no C0000005 reports, that these had been eradicated from VFP and all caused by external forces. The SP1 delivery proved that one wrong.

We have been in the dark about VFP errors for some time now and it keeps getting darker all the time. MOST of the fixes in the SP1, for instance, were never listed a BUGS in the (alleged) bug list in the first place.
