Segfault in precompile on Julia 1.0.4

[PallHaraldsson]

I just posted the segfault today here: JuliaCN/Py2Jl#5 (comment)

I checked out master for that project, but since there's since been one update, so you may need:
(v1.0) pkg> add https://github.com/JuliaCN/Py2Jl.jl#0dbff54

The (still open) issue #31240 may be the same. It's months old, and the segfault there looked sufficiently different to me, to at least not be sure it's a duplicate.

Some strange thing, may or may not be important: https://discourse.julialang.org/t/compatibility-across-julia-1-versions/27196/22?u=palli

Julia 1.1.0-rc2 is known to work, but no 1.0.x (nor really later versions, while they do not segfault), see more at: JuliaCN/Py2Jl#6

If it helps people then strangely this works (at least in some Julia version):

(v1.0) pkg> test Py2Cl

with it running tests I can't run manually. The above must imply "using Py2Cl" that fails for me manually.

It segfaulted in 1.0.4 but while 1.0.5 errors (it seems like a package issue), at least for this package it doesn't segfault in precompil, so I assume precompile fixed in Julia (for all) packages.
