Failed to precompile in 1.0. LoadError: syntax: try without catch or finally

[thehalfspace]

I am unable to precompile JLD in Julia 1.0 version. It worked fine in 0.6.

I would have switched to JLD2, but JLD2 can't open JLD files, which I have a lot of.

https://github.com/rssdev10/JLD.jl/tree/julia-1.0 - compilable and can be used if you need some basic functionality or stub only.
But package tests are not working.....

Next step: master...rssdev10:julia-1.0

The error in the code:

function gen_jlconvert(@nospecialize(T))
    typeinfo = JLCONVERT_INFO[T]::JldTypeInfo
    if isa(T, TupleType)
        return _gen_jlconvert_tuple(typeinfo, T)
    elseif isempty(fieldnames(T))
        if T.size == 0
            return T.instance
        else
           return :(_jlconvert_bits(T, ptr))
        end

return T.instance generates UndefRefError: access to undefined reference

Moreover, already Type{Int64}.instance generates same error. Any ideas?
