I've encountered this problem several times now and almost always it takes
hours or days to reduce crashes down to this.
The sizeof property works as expected for static arrays, but as soon as
you change the array to a dynamic one (e.g. cause it became too big to
stay on the stack)
.sizeof doesn't return .length * elem.sizeof anymore but only the size of
the struct consisting of .ptr and .length.
This is really error-prone and I need the actual size of an array while
interfacing with C a lot.
Any way to avoid this? Maybe a dmd warning if possible?
Please don't "just use .length * elem.sizeof" me. It's cumbersome and a
bit error-prone as well. If you hard-code the element type and the type
changes later -> bang.
I know I could use a function but this doesn't change the problem that
.sizeof works perfectly for static arrays and silently crashes when
changed to a dynamic one.
