oops.  i think i hit "email" instead of "reply".  oh well, i'll post it here
for public reference as well.

adding an opCmp() declaration to the struct seems to fix it.

struct A
{
 int opCmp(A other)
 {
  return 0;
 }
}

int main()
{
 A[] array;
 array.sort;
 return 0;
}

probably what's happening is that structs do not have a default opCmp as
classes do.  though it would be nice if the compiler flagged an error saying
that you need to define an opCmp to sort a struct array.  :)
