Indeed. After spending quite a while whittling down my code, I've
posted the following snippet as issue #7599:

Good point. If the data is packed, you can toss an align(1) on the front
of the struct declaration.

Just looked at my old C++ code. And the struct looks like this:
struct TaqIdx {
char symbol[10];
int tdate;
int begrec;
int endrec;

So I am guessing I want to use the align(1) as Justin suggested. Correct?
Yes.

In the case of empty array slices, ptr can point to anywhere. But then,

Arrays treat null kind of funny. For equality, null is considered to be the
same as an array with length 0. So,
