Hi, Recently, I let VS2005 convert the msvc7 project to vs8. No problem at all! However, when I tried the tutorial example I got an asEXECUTION_EXCEPTION. This happens when the script uses Print(). I guess this is due to the new VS2005 compiler or that I've missed something in my configuration. Any thoughts about this issue would be appreciated. Regards, topcatse

VS2005 works fine for me. I'll try the example tonight. I recommend re-creating the project files anyway.

OK, I'm glad to hear that it works for you guys!

Unfortunatly, I'm still having the same problem. It's interesting that when I switched back to 2.4.1d the tutorial worked fine but not with 2.5.0a. I will try 2.5.0a on WinXP now to see if I experience the same problem.

Here's some information from a debug session of the tutorial sample if some is interested.

The exception is generated in asCContext::ExecuteNext(), row 2130:
case BC_ChkNullV:
{
// TODO: Pointer size
asDWORD *a = *(asDWORD**)(l_fp - SWORDARG0(l_bc));
if( *a == 0 )
{
byteCode = l_bc;
stackPointer = l_sp;
stackFramePointer = l_fp;

SetInternalException(TXT_NULL_POINTER_ACCESS);
return;
}
}

Looks like the tutorial sample is triggering a bug in the library. It's possible that this is the same bug that I fixed for 2.5.1 WIP 1 (which Villemon found in 2.5.0a). You could try the WIP version, if you want. It should be backwards-compatible with version 2.5.0a.

I will be releasing a new version of 2.5.0 with the bug fix, when I get the chance to actually make sure that the fix corrects the problem.
