CVI2009 The program has caused a 'General Protection' fault

[nickb]

Hello Jan -

Thanks for the information - it's been a great help in narrowing down the cause of the issue.  

Yesterday I was able to create a small program that recreated the crash you were seeing, and as a result, we've been able to carefully characterize this issue.  The bug ID for this issue is 201259.  Unfortunately, due to the nature of the issue, there does not appear to be an easy workaround for you.  The only thing I can think of is that because the root of the issue lies in removing WinMsgCallbacks, if you were to synchronize around removing those callbacks, the issue should go away.  However, I certainly realize this would be a pretty major change to your code, and likely unacceptable.

Just curious, what is the urgency of this issue for you?  We will certainly fix this for the next release of CVI, but because CVI 2009 has just released, the next release quite a ways away.  Is this fix something you can wait for, or are you stuck in your tracks?

Thanks, and sorry for any inconvenience,

NickB

Hi NickB,

We would like a patch for this in the next couple of months. The next version of our application was planned to be released in April. The bug does not affect us during the development phase.

We do understand that you want to stick to your release schedules, but we would appreciate a downloadable  fixed RTE. If I remember correctly, you have issued downloadable fixes before.

Thanks for very good support regarding this matter.

Has this issue finally been solved in an release?

I also see a 'General Protection' fault that appears to be a race condition.
