Handle Int32 matrix dimensions in ConsecutiveParamSparseMatrixCSC (Julia 1.12 x86 CI failure)

[Copilot]

The Tests 1.12 - ubuntu-latest - x86 - push workflow failed in steady diagnostics due to a constructor dispatch mismatch: ConsecutiveParamSparseMatrixCSC was called with Int32 dimensions, but only Int64-typed dimension constructor dispatch was available.

• Root cause

  • create_from_nz can produce Int32 nrows/ncols on this CI target.
  • ConsecutiveParamSparseMatrixCSC required m::Int64, n::Int64, causing a MethodError in the diagnostics path.

• Code change

  • Added a narrow outer constructor in ParamSparseMatrices.jl:
    • accepts m::Integer, n::Integer
    • forwards as Int(m), Int(n) to existing constructor
  • Keeps existing storage/index typing (Ti) and data typing (A<:AbstractMatrix{Tv}) unchanged.

• Regression coverage

  • Added a focused test in test/FEM/param_data_structures.jl to construct ConsecutiveParamSparseMatrixCSC with Int32 dimensions and verify structural invariants (innersize, nnz, type parameters).

function ConsecutiveParamSparseMatrixCSC(
  m::Integer, n::Integer,
  colptr::Vector{Ti}, rowval::Vector{Ti}, data::A
) where {Tv,Ti<:Integer,A<:AbstractMatrix{Tv}}
  ConsecutiveParamSparseMatrixCSC(Int(m), Int(n), colptr, rowval, data)
end
