Precompilation error due to WeakRefStrings

[junglegobs]

Perhaps an issue with WeakRefStrings itself, but I get the following errors when trying to use CSV on Julia 1.6.2. See also this discourse post

i think in order to see what went wrong we'd need the full error message, which you can get by using the packages after precompile failed e.g. using WeakRefStrings, CSV or by running precompile with using Pkg; Pkg.precompile()

[junglegobs]

Apparently, this is due to this bug

[junglegobs]

It is.

[HaoxueYue]

define a mutable struct in WeakRefStrings.jl package:

mutable struct PosLen 
    pos::Int
    len::Int
    missingvalue::Bool
    escapedvalue::Bool
end
