Move data to structure fields without copying [message #79465]

IDL gurus,

Is there a way of getting an array in a structure without copying it?

data=fltarr(89,1192,1192)
struct={data:temporary(data),...}

Using temporary doesn't seem to work in this instance on a 32-bit
machine (not enough memory). I also want to avoid using pointers

data=fltarr(89,1192,1192)
struct={data:ptr_new(temporary(data)),...}

This does work, but I will need to adapt all further use of the
structure (god forbid) and it doesn't seem worth the effort because
one day, I will have an array that can't be allocated on 32bit at all.
Any suggestions?

Cheers,
Wout
