If I have less than 33 GB free space at /var/tmp/portage, 'emerge -v1 rust' fails. If I increase the free space to 35GB I can emerge rust, but I see that rust needs more than 33 GB on /var/tmp/portage: root@lynx:/root(15)# df ; du -s /var/tmp/portage/dev-lang/* Filesystem 1K-blocks

dev-lang/rust-1.19.0::gentoo was built with the following: USE="clang doc -debug -libcxx" ABI_X86="(64)" On an other system with MAKEOTPS=-j5 4GB free space under /var/tmp/portage seems to be enough speace for emerging rust-1.19.0.
Hi, it's your -ggdb CFLAG affects rust build. it produces enormous binaries bith. Check your other machines, most likely they do not have -ggdb. On my machine the initial build was about 14gb with -ggdb and I needed at least double the size to perform the merge, so the requirement is more than 34gb for sure. It did not fit into the tmpfs of my lapto =) So I believe this bug is a duplicate of https://bugs.gentoo.org/show_bug.cgi?id=626134
