Well since recs is array of pointers this looks like a null
pointer in your data.
The usual ways to fix that is either print stuff or poke around
in debugger to see if a Record* is null or .name is null.
The problem is that although the "recs" array is declared as
having 10 pointers, not all pointers are used. In the qsort
case, the second argument limited the sort to just the first
n_recs (valid) pointers. There doesn't seem to be a way to tell
std.algorithm.sorting.sort to only look at part of the fixed
array.
I managed to get it working by declaring a D dynamic array,
appending n_recs pointers to it and using it as argument to sort.
Unfortunately, I then had to copy from the dynamic array to the
fixed array in order to continue using the latter. Any shortcuts
around this?
