Does this fix the unreproducible behaviour of Julia? As described in
this bug [1] and discussed at length for v1.3.

Because my machine (of lockdown) is not enough powerful, I cannot
rebuild Julia v1.4.1 with the option '--check'.
Could you report the status on the reproducibility of Julia with this
new version?


BTW, thank you for this important update!
Hope to play with it soon.
