Can you attach a copy of the input file that caused the crash?
Created attachment 1109052 [details] last input file processed The input file has been modified by an awk script, but I made many attempts and I cannot remember the version related to this crash. As I am just a beginner with awk, the awk script probably did something strange. However I will send you the input file, but if it happened to me only, I think we can ignore this crash.
