build.log

I can not build dev-lang/zig-0.5.0 on this system (tested with cmake.eclass as well as cmake-utils.eclass, that does not make a difference).

Portage 2.3.84 (python 3.8.1-final-0, default/linux/amd64/17.0/desktop/plasma, gcc-9.2.0, glibc-2.30-r3, 5.3.11-gentoo x86_64)

Comment 1 Nick Erdmann 2020-01-06 22:56:54 UTC 
Unfortunately I cannot reproduce this issue. However, according to your build log, zig crashes in /var/tmp/portage/dev-lang/zig-0.5.0/work/zig-0.5.0/lib/std/build.zig, line 1841, due to an unhandled error. Following the code back to the error's possible origins, it was most likely caused by resource exhaustion. At this step, zig uses a considerable amount of memory on my machine. Your machine has been swapping. Have you checked if this may have caused the build to fail?
Comment 2 Aisha Tammy 2021-04-22 15:00:18 UTC 
this zig version is no longer present in gentoo
