Segfault with PackageCompiler and Unitful on Julia v1.5 (regression)

[oschulz]

Using PackageCompiler with Unitful now crashes on Julia v1.5.3 but works on v1.3.1 and v1.4.2:

Using a "precompile_exec.jl"

using Unitful 

# PackageCompiler crashes here:
u"m"

and running

import PackageCompiler, Libdl

PackageCompiler.create_sysimage(
    [:Unitful],
    sysimage_path = "JuliaSysimage.so",
    precompile_execution_file = "precompile_exec.jl",
    cpu_target=PackageCompiler.default_app_cpu_target()
)

results in

on Julia v1.5 (Linux x64_64). On Julia v1.3.1 and v1.4.2, this runs fine and produces a functional system image.

Tested using PackageCompiler v1.2.3 and Unitful v1.5.0 (no other packages in environment).

#38049 broke it.

Fixed by #38399.

Was a mistake to backport it -.-

Thanks @KristofferC ! Do you know if there will be a v1.5.4 before v1.6?

[oschulz]

Oh, and should I close this, then?

[KristofferC]

Thanks @KristofferC ! Do you know if there will be a v1.5.4 before v1.6?

I am not sure. I think @NHDaly said the might push for a 1.5.4 release, but again, not sure.

[oschulz]

Thanks - I'll close this for now, then.

Lemme know if I/we can help with that in any way~
