dev-util/electron-1.6.16 checks for at least 5 GiB disk space, but it needs 11 GiB, maybe even more. It is possible that only when USE="lto" is enabled. My tmpfs is 8 GiB and it is definitely not enough.
Are you using gcc-7? It seems to have regressed vastly in comparison to gcc-6 with respect to the disk space used by LTO object files.
no, I have gcc-6.4.0 emerge --info Portage 2.3.24 (python 2.7.14-final-0, default/linux/amd64/17.0/desktop/plasma, gcc-6.4.0, glibc-2.25-r11, 4.15.4-gentoo x86_64)

Quick check using du -s every 30 seconds gives for dev-util/electron-1.6.16/ this: gcc6 +lto 11171596 gcc7 +lto 107594488 gcc6 -lto 4263696 gcc7 -lto 4275704 so there is definitely a problem using lto and gcc7.
