Hi all,

I'm working on a debugger for my AngelScript implementation and I'm wondering if it supposed to be allowed to have object handles pointing to Array's?

For example:

array<int> a = {1,2,3};

array<int>@ aptr;

int arrayValue = aptr[1];

seems to be an accepted script (using the Array addon).

The engine seems to stall at the 3rd line. Should the engine be throwing an error at compile time?

Best regards,

Jim

While the compiler could deduce that aptr[1] is a null pointer access, it is valid to have array handles and to access them in that way.

What do you mean by 'The engine seems to stall at the 3rd line'?

The asIScriptContext::Execute should be returning -3 (asEXECUTION_EXCEPTION) when reaching this line, not stall. You can get more information on the exception that occurs (should be a null pointer access) by querying the context (see the GetExceptionInfo function from the helper add-on for one way of formatting the information into a human readable string).
