Node of course uses V8. V8 dropped support for armv5 by removing it's no-vfpv2 port starting with v3.18
Nodejs switched from node v3.17 to v3.18 between 0.11.0. and 0.11.1 only the previous stable branx v0.10.x still uses V8 version below v3.18
The switch of nodejs versions yesterday from 0.10.36 to 0.12.0 means that armv5 support is gone. I don't even know how a build for 0.12.0 succeeded. as it is the binaries segfault.
currently I have fetched the old PKGBUILD for 0.10.36 from the gitrepo and will have to wait a few hours for it to build.
I don't know if the solution should be to split of a nodejs10 PKGBUILD or to just drop nodejs building for armv5. my preference would be the former.
Thanks for being an awesome community guy, I know your working hard.
