Runtime Error: Pure Virtual Function Call R6025

Hi,

I am currently being plagued by the error:

Runtime Error: Pure Virtual Function Call R6025.

It is difficult to tell what is calling this. There don't appear to be any trends to it and it has started happening when running new scripts as well as old tested ones.

I would really, really like to figure out how to stop it doing this. I have used MEL to create my Masters thesis and this bug is basically undoing all my hard work.

Please help if you know anything about this error on Windows 2000.

Thanks!

I've never seen this. Can you supply some more information. What version of Maya. What is you mel script doing. Is your mel script using mel commands from your own custom MPxPlugins or just built-in Maya mel commands. Do you have multiple versions of maya on your machine. Is there any information printed to the Maya Script Editor window when you get the error.

I am using Maya 4.0 and 4.2 (both cause the crash). The only commonality between the scripts that cause the crash is that they both use "draggerContext". What is really strange is that this error never occured when I was writing the first script, and I have not modified that script, but it now occurs regularly - even when no other scripts have been called.

I can only think that something has changed somewhere in my user settings. But the scripts run perfectly on Maya 3.5 PLE for Mac. I decided to download the Mac version as I was certain there was nothing wrong with my scripts and Maya was causing the crash - and sure enough they work flawlessly on the Mac. Unfortunately I plan to use these with a Calcomp tablet and can't get drivers for the Mac. I also want to use the depth map shadow feature in 4.0.

So basically I'm in quite a fix unless I can sort out this error.

If you think it is your prefs, then find your prefs directory and rename it to prefs_old. When Maya 4.0 starts, it won't find a prefs directory and will make a brand new one with fresh prefs. If your script works, you know there is some problem in your old prefs. When doing this test, make sure you don't have pref folders around from an older version of Maya, like 3.0 prefs.

Make sure you have the correct graphics drivers installed. We had machines that were crashing when doing an extrudeFace under 4.0. Those machines had older graphics drivers that worked fine under 3.0 but caused problems under 4.0. As soon as we replaced the drivers, the 4.0 machines were fine.
