You are using a static-memory version of sander (i.e. without -DMEM_ALLOC
set when you compiled.) This means that the value of lastist you enter
is not used. As the message above indicates, you need to edit sizes.h
and recompile.
Given the message above, I have no idea why you should get a core dump: that
message should lead to a graceful error exit, with no segmentation faults.
But try to changes the sizes.h file and see if that helps.
...good luck...dac
