[Octave-bug-tracker] [bug #53544] -Wclass-memaccess warnings

[John W. Eaton]

Follow-up Comment #2, bug #53544 (project octave):

I hope there is a better way, but does the attached patch avoid the warning?

I think the problem is that octave_intN and octave_uintN types are classes,
not POD types, so passing a pointer to an octave_intN object to memcpy is
questionable.  But we know it is OK because these objects contain only a
single data member that is the corresponding intN_t value.

This problem comes up often because sometimes we want an array of octave_intN
objects and sometimes we want an array of intN_t objects.  Maybe we can use
some template specializations to do better than the current fortra_vec
function.  That's something we can look at after the release.
