Very few here will be able to make sense of that, especially without you sharing more details about what you’re doing and showing us some code for how you are handling the XML.

Exception code 5 basically means something tried to access memory it wasn’t allowed to access.
Mostly this is due to mismatched dll’s somewhere, eg trying to use clarion6 stuff in clarion10, something like that. But could be any number of problems.

To help, try using the debug library in /bin/debug that gives a LOT more info in your exception, like procedure names and source code lines.
You can also help by compiling in debug mode.

Once you have the extra info the solution might be obvious to you.

Also, as well as what @seanh said, this can be cause by trying to access a class that hasn’t been instantiated. For instance

st &StringTheory
  CODE
  st.SetValue('Some Value')

In this example, st is a pointer to a StringTheory object, but it hasn’t been instantiated, leading to the Access Violation (C0000005) error.

Hi Sean

Does Clarion 8 have the DEBUG RTL?

Yes it does

@mfthrzy you need to compile with your project set to Debug and follow these instructions to see the Call Stack with procedure names. As noted we also need to see what code you are running? How are you reading the XML?
