MallocArray of MallocMatrix

[Thomas008]

I would like to use StaticTools to compile a MallocArray on MallocMatrix. StaticTools is very great e.g. to represent Strings in a MallocMatrix. When initializing a MallocArray on MallocMatrix, I get an AssertionError:

MallocVector{MallocMatrix}(undef,3)

Then I get

AssertionError: Base.allocatedinline(T)
Stacktrace:
 [1] MallocArray
   @ StaticTools C:\Users\T460\.julia\packages\StaticTools\BAWnD\src\mallocarray.jl:112 [inlined]
 [2] MallocVector{MallocArray}(x::UndefInitializer, dims::Int64)
   @ StaticTools C:\Users\T460\.julia\packages\StaticTools\BAWnD\src\mallocarray.jl:131
 [3] top-level scope
   @ REPL[47]:1

How can I initilize a MallocVector in MallocMatrix? There was already a similar issue. The solution was about redefining Base.allocatedinline(T), or Base.unsafe_load and Base.unsafe_store (?)

The problem is that MallocMatrix is an incomplete type; you need to fully specify the type.

julia> MallocMatrix
MallocMatrix (alias for MallocArray{T, 2} where T)

julia> MallocVector{MallocMatrix}(undef,3)
ERROR: AssertionError: Base.allocatedinline(T)

Great! I understand. Thank you a lot!
