Error messages after starting the blink process

When I just finished the WBPP script, I wanted to inspect the results, so opened the Blink process.. then this happened:


*** PCL Win32 System Exception: At address 00007FFC9C17663E with exception code C0000005 :

This cannot be reproduced under normal working conditions, on any of our working and testing machines.

You don't provide any information about your hardware, software and operating system. However, the backtrace clearly shows where the problem has happened, which is useful. The access violation is being triggered by the QImageData::~QImageData routine, which belongs to the Qt library. This is a mission-critical, fundamental routine that destroys a screen image and releases the memory it occupies. This routine is called all the time during PixInsight execution. The probability of a bug in this routine is virtually zero, or otherwise all Qt-based applications, including PixInsight, would be generating access violation errors all the time, and an industry-leading software library such as Qt would be a total failure.

This is probably a bug in your graphics driver, in a system component, or a memory management problem. Memory exhaustion conditions can generate these problems frequently on Windows. This is not a bug in PixInsight, but a machine-specific issue, unless you can provide a data set and/or a repeatable sequence of steps to reproduce it consistently.
