Created attachment 378718 [details] build.log While building dev-libs/libnl-3.2.24-r1 with MAKEOPTS=-j5, I got several errors which suggested the compiler was trying to read a corrupt or incomplete file: netlink/genl/capi_wrap.c:1:1: warning: null character(s) ignored [enabled by default] netlink/genl/capi_wrap.c:103:3: error: unknown type name 'SWIGINTERN' netlink/genl/capi_wrap.c:103:23: error: expected '=', ',', ';', 'asm' or '__attribute__' before '*' token [...] Rerunning the build made the problem go away, so I suspect a race condition, though I don't have time at the moment to dig deeper. build.log attached. emerge --info: Portage 2.2.10 (default/linux/amd64, gcc-4.7.3, glibc-2.17, 3.14.6-gentoo x86_64) =================================================================

I'm pretty sure this was fixed in 3.2.25. Perhaps by [1]. In 3.2.24 I see this: running build_ext building 'netlink/_capi' extension swigging netlink/capi.i to netlink/capi_wrap.c swig -python -O -nodefaultctor -o netlink/capi_wrap.c netlink/capi.i building 'netlink/_capi' extension swigging netlink/capi.i to netlink/capi_wrap.c but versions beyond that don't seem to do this twice in quick succession any longer. https://github.com/thom311/libnl/commit/425d3d6661b7b25bc6058dbfb01d984f21b73f54
