Previous summary: dev-qt/qtwebengine can fail to build with 16GB RAM or less and >=12 "cores" (counting threads)
As per description, there are some common hardware configurations that will cause the OOM killer to do its thing when building dev-qt/qtwebengine. I experienced this when testing 5.15.2-r1 on one of my laptops.
This is caused by MAKEOPTS being set automatically by Portage based on the number of cores, but there not being sufficient RAM.
I have a workaround for this in several ebuilds such as webkit, which will set MAKEOPTS based on the number of real cores, not virtual cores, since this can half memory consumption with a minor performance impact, and also scale back number of cores further on systems with less memory. These should be applied to qtwebengine as well.
