Segfault when using the mold linker

[MasterDuke17]

The archlinux package (https://aur.archlinux.org/packages/dwarfs) segfaults during the build with the mold linker. It does build just fine when not using mold.

Thanks for the report.

I saw this myself shortly after releasing v0.9.9. I might have set the default for DISABLE_MOLD to ON if I had noticed this earlier.

I think this is a bug in mold and I've reported it here. It looks like there's already a fix, but it has yet to be released.

This is fixed in mold-2.31.0.

It is also independently fixed in dwarfs-0.9.9-2 (AUR) by disabling the use of mold when building.
