Hoi Floris,
thanks for the detailed report.
You did not by any chance also print the content of variables in the
vincinity of the code where the segfault occured?
E.g., "bid", "ii", "batlist[ii]"
Or do you still have your debugger with Mserver running (or have a core
dump) and could hence still print these values?
Thanks!
Stefan
