Windos 7 error message

[DeFleur]

Occasionally I'm getting a Windows 7(64 bit) error message since CF3.05.v34
quote file name: image - value must not be below zero unquote.
In such case CF3 crashes and I've to un- and re-install same. Mystery or bug ?

Sounds like a bug. When does this happen? What are you doing when it happens?

[DeFleur]

It may happen or not when rendering the same cfdg file. I have not found a logic
trigger yet. In one example I render .cfdg files I write by Processing into the Sketch folder
with 10'000 (100x100 pixel type) shapes. In such case it happens more often. In
another case I translated a CF2 file into a CF3 file and then it happened but
without repeatedly reproducing the error message. However, these are indications
but not reproducable observations each time of rendering.

How much RAM do you have? The 64-bit release build keeps much more shapes in memory before spilling them to temporary files. My development system has 8gig of RAM so I never noticed a problem. But it may not be so good for people who have 2gig of RAM or less. My current developer build checks out how much physical memory there is and scales back the memory footprint if there isn't very much.

[DeFleur]

I've 4gig RAM and a 3.75gig ReadyBoost USB stick.

I think that the problem is that I assumed that 64-bit programs could automatically allocate more than 4GB is memory. This is true on Mac and Linux. But on Windows you have to set a compiler flag to enable >4GB memory even if your program is 64-bit. I didn't set this flag. I can put up a new release for you to test if you wish.

[DeFleur]

Thank you for the effort. I propose first me to wait till the error message appears again
and is reconfirmed. I then document/inform as much as possible. Then I work with your
update for testing. You agree ?

[MtnViewJohn]

Sounds good. Thanks.

Here is the Window 7 error message again as it appeared again but is in German.
As mentioned it states value must not be below Zero re file Image and it seems it relates
to jitDebugging (??)
************** JIT-Debuggen **************
Um das JIT-Debuggen (Just-In-Time) zu aktivieren, muss in der
Konfigurationsdatei der Anwendung oder des Computers
(machine.config) der jitDebugging-Wert im Abschnitt system.windows.forms festgelegt werden.
Die Anwendung muss mit aktiviertem Debuggen kompiliert werden.

When appearing it necessitates to de- and re-install CF3.
Specific or General ?

There is a .Net variable that Context Free sets to a value less than zero and this causes Windows to report an error and ask if you want to drop into the debugger to analyze it. I will try to track down how this is happening. I'm amazed that you have to reinstall Context Free to stop it from crashing.
