I'm running PI Core version 1.8.8-7 x64 (2020-12-17) on the latest instance of Win 10 Pro (x64) an MSI i3 CPU desktop.

This morning I had previously been opening/closing FIT files using the format convertor script as well as the blink process to make an AVI file. I then had one FIT file open to look at its header details. When I closed the header viewer followed by the file, I noticed the following exception indicated in the process console:

Opening 1 file(s):

This, I'm sure, will mean more to you than it does me. PI continued to run but as a precaution I closed and re-started the application.

This cannot be reproduced. This crash is not a PixInsight bug. Check your graphics drivers and make sure you have the latest versions installed. Also consider a complete, clean reinstall of your operating system.

9: QImageData::~QImageData in module: C:\Program Files\PixInsight\bin\Qt5Gui.dll at address: 0x6E9E65C0

The crash is happening in a routine that cannot fail under normal working conditions. QImageData::~QImageData belongs to the Qt library, and the probability that such a fundamental routine can contain a bug is so small that this crash can be regarded as a machine-specific issue, unless you can provide a repeatable pattern or a data set where the same problem can be reproduced consistently.

I have the same issue as above. This is confirmed not a windows or machine problem.

This only happens when I use the PI BLINK module. This has also happened on two prior PI releases and on two different Windows 64-bit OS's machines. This does not happen all the time. I verified on a vanilla start with no other other processes running.

All drivers and system files are current and up-to-date.

I have a complete Windows event error log which it says it's an appliction error below this PI backtrace information

Today I experienced another instance of the memory violation, but under slightly different circumstances to my initial report.

Having successfully using 'Blink' to review 225 frames, each 4.073 KB FITs, I then used the 'Close all images' button to conclude the use of 'Blink'. At which time the 'Process Console' report a memory access violation, as detailed in the back trace information given below:

* Blink: Releasing memory...

I'm running the same PC standard as in my initial report, i.e. PI Core version 1.8.8-7 x64 (2020-12-17) under the latest instance of Win 10 Pro (x64) on a MSI i3 duel core CPU desktop.

After experiencing repeated PI memory access violation reports, and having to then re-start the PC due to it destabilising other applications, e.g. Outlook 365, etc, typically causing them to report 'Not Responding', or the PC going into serious snails pace, herewith is the latest example of text from the Process Console:

*** PCL Win32 System Exception: At address 00007FFF9B4F663E with exception code C0000005 :

The repeated stoppages are seriously undermining my use of what has up till now been the workhorse of all my image processing. I for one would be most disappointed in having to move away from using PI. :-(

I've heard tell that PI might not clear or release memory or its image cashe when it should; this may be true or purely anecdotal. What I do experience, however, is that if I've had an image open and run but then undone processes on it. When I close the image but still have PI running, I then cannot delete that image from within File Explorer, until after I've closed PI. This does seem to indicate that for whatever reason PI keeps closed image files locked in some way? If I then get this memory access violation problem and thus exit PI, those image file often remain locked until after a PC restart. There is obviously some inter-relationship going on in this regard.

I do hope this isn't regarded as 'not a PI issue', since clearly there is a real problem here albeit a difficult one to find the route cause of.

As noted above, this is a machine-specific issue unless you can provide a repeatable pattern or a data set where the same problem can be reproduced consistently. We cannot reproduce it on any of our working and testing machines under normal working conditions.

This might be a bug in your graphics driver, a problem caused by wrong or corrupted system components, or the result of a wrong interaction with some third-party application. We cannot know the reason because we cannot have control over it. I know this is not what you want to read, but we cannot solve a nontrivial problem that we cannot reproduce and understand.

I've heard tell that PI might not clear or release memory or its image cashe when it should; this may be true or purely anecdotal.

Interesting. Again, none of these things have been demonstrated and/or reproduced under normal working conditions.

I did have this problem too, yesterday, on my windows laptop. During ImageIntegration. Running Windows 64, and latest update of PI.
*** PCL Win32 System Exception: At address 00007FFF9B4F663E with exception code C0000005 :
Access violation: invalid memory read operation at address 000000269AC3ACC0

(not exactly sure about the 000000269AC3ACC0)

Afterwards it did not happen again, although I worked a lot on the laptop with PI.


On my desktop, I presume it was not the same, as there I had this weekend three complete system crashes, using PI, with the Bug Check 0xBE: ATTEMPTED_WRITE_TO_READONLY_MEMORY

The desktop is a complete new system, new CPU, new disk, new windows.

I have a question running on that problem : https://pixinsight.com/forum/index.php?threads/memory-exhaustion-problems.16474/#post-99578

This one is completely different and has nothing to do with PixInsight. This is a system software problem:


So this problem is being caused by one of your device drivers.
