The reason it doesn't work is scope(exit).

Looking at the code[1], it doesn't look like the scope(exit) is really
necessary here (I don't see why it should catch exceptions thrown by parse), so
until there's scope(...) CTFE support, a simple fix would be to rewrite the
code as:

    auto result = parse!T(v);
    if (v.length)
        convError!(SV, T)(v);
    return result;
