CellProfiler ver. 3.1.8 gives a strange message and crashes

Hi. I figured this could be the place to ask this question. I am using CellProfiler on a HP Z420 workstation with 64 GB RAM and for the first pile of images CellProfiler does a good job. However, after the first 33 images I get this error message. If I start over again or continue from the next file it crashes again after app. the same number of images. I don’t suspect this to be a matter of RAM and the error message also contains a C++ part, so this is maybe where something goes wrong. Cell%20profiler%20error
Continue processing does not work and the program crashes. The biggest problem is that I never get the numbers out and have too many image to do it manually in smller chunks. Any suggestions? Thanks in advance. Thomas
