Answer 1

I have been caught out by this type of "indicated error" during Delphi debugging.

Check if you have any watched variables with "Allow Function Calls" enabled or watches that try to show other variables in the same unit (or global) that might be uninitialised. When stopping on a breakpoint this can cause Delphi's debugger to attempt to display the value via a function call that accesses an uninitialised Pointer or variable. The actual variable that causes the AV my not even be on your watch list.
