Very often - when I save my development image (including Seaside, SST, etc) and restart it later again - I get exceptions from that method., because the method tries to free external memory, which is not available any more (general exception fault is thrown).
The best way would be to free potential objects when starting this image (with exception handling) or to initialize this object at startup. I do not think, that there can be any valid OSObjects at startup of an image. -- You received this message because you are subscribed to the Google Groups "VA Smalltalk" group.

Marten -
What version of VA Smalltalk do you see this happening in (and what platform)? I know there used to be a problem with #freeBuffer:, but I thought it got fixed.

That's for 8.5 (under Windows), but I've seen this under Linux also - and I think it was also under 8.03

Hi,
I got it today. For the first time. There's nothing helpful the debugger could tell me about it, but OSUInt8(OSPtr)>>#free fails due to GPF during processing of the finalizeQueue...

I now see it almost every time I start an Image in which there was a running WASstAdaptor before the image got saved.
VAST 8.5 on Win 7, Win XP SP3 and ubuntu 11.10. A second or two after the image opened, the debugger pops up. You can terminate the process without any problems and continue to work. Here's the stack trace, but I guess it's not really helpful: Debugger Stack Trace Report: Error String: 'Primitive failed in: OSPtr>>#free due to General protection fault' Resumable: false Process Name: Idle 20:27:36 Process State: suspended Priority: 1 GPF Information: Handler=0xf74a79ac vmState=0x00000002 vmError=0x00000034 Signal=0x0000000b GS=0x00000063 FS=0x00000000 ES=0x0000002b DS=0x0000002b EDI=0x00000002 ESI=0xf4d35ed3 EBP=0xfff7ef38 ESP=0xfff7ef0c EAX=0x00000000 EBX=0xf72c9ff4 ECX=0x09c49af8 EDX=0xf434c1d0 TRAPNO=0x0000000e ERR=0x00000004 EIP=0xf71c688e CS=0x00000023 EFL=0x00210202 UESP=0xfff7ef0c SS=0x0000002b Executing in: OSUInt8(OSPtr)>>#free System Configuration Dump Copyright: VA Smalltalk V8.5; Image: 8.5 [194] VM Timestamp: 4.0,(NC) 8/17/2011 (82) (C) Copyright Instantiations 1994, 2011.

Hi again,
is this one fixed in 8.5.1? A packaged image should ideally not be affected by this, because there should never be a saved open socket or http session in it, but if there is for some reason, this might crash a server image right after its start.

In reply to this post by Marten Feldtmann-2
Marten - The problem is caused by stale entries in the finalization queue when the image is started. I will be changing the EmSystemConfiguration>>#initializeVM method to clear the finalization queue for V8.5.2.
