Context: The following command causes a dead-lock in 1.4.0-DEV.407 (2019-10-31) and likely also in 1.3. It works fine in 1.03 and 1.2.
x = WeakKeyDict(:a1 => 4) push!(x, :a2 => 2) # WARNING: deadlock here
I thought I could add some
println statements in
setindex!in ‘weakkeydict.jl’ and then
include the modified file. Not unexpectedly this didn’t work but I wonder if there is a possibility to change Julia code and then take into account the changes? I rebuild Julia with the
make command which worked but took a long time.
(Regarding dead-lock: it hangs when executing https://github.com/JuliaLang/julia/blob/4f649c207a97104d7eb1b9bc3e486d39522f4a5e/base/weakkeydict.jl#L81)
