Check whether `isbits(cdCanvas) == true` (probably not). If not, try
changing it to an immutable.
Aside from that, `Ptr{Void}` should be correct as the field type. This
construct is used frequently; see e.g.:
https://github.com/staticfloat/Nettle.jl/blob/97268c4764cf4a84b16208628224e36d49a469ec/src/hash.jl#L20-L28
