There's no default-init here, neither in > the original Dolphin code nor in the small example supplied in comment #0. > Clang rejects the variant with default-init, accepts without. right the difference is init-capture vs simple-capture. This is a simple-capture https://eel.is/c++draft/expr.prim.lambda.capture#6 only talks about init-captures.
