[Monetdb-developers] Some help to understand this error output from m5...
I am using monetBD5 with datacell module and I got the following crash. I know it is related with memory map and maybe a valgrind execution would be a nice thing to do. However, I would like more feedback from the experts:

The datacell module is not available outside CWI.
I know it is related with memory map and maybe a valgrind execution would be a nice thing to do. However, I would like more feedback from the experts:
Yes, the first step is to run the program with valgrind. This probably indicates a double free with all the consequences of that.
