The IllegalTypeAnalysisException / SCCNonlinearProblem segfault that gated this test on `VERSION < v"1.11"` is fixed in Enzyme 0.13.148 (closes EnzymeAD/Enzyme.jl#3026). Verified `Enzyme.gradient` over the SCC loss returns the correct gradient on Julia 1.12.6. Leaves the comment about the vector-based SCC heterogeneous-function limitation (Enzyme.jl#3021) since that's a separate API question, not a Julia-version issue.

Summary
test/scc_nonlinearsolve.jl'sEnzymetestset was gated onVERSION < v"1.11"because of anIllegalTypeAnalysisException/ SCCNonlinearProblem-worker segfault on Julia 1.11+. Enzyme 0.13.148 (released 2026-05-21) closes EnzymeAD/Enzyme.jl#3026 which fixes it.Locally verified on Julia 1.12.6 + Enzyme 0.13.148:
Enzyme.gradientover the Tuple-based SCC loss returns the correct gradient (matches FiniteDiff to 5% as the existingrtolexpects). Full file: 8/8 passing (was 7 Pass / 1 Broken).Refs
